A Montessori–Reggio Emilia-Inspired Social-Emotional Learning Studio

 The Social-Emotional Intelligence Classroom: A Montessori–Reggio Emilia Approach to Executive Function, Empathy, and Self-Regulation

This educational framework merges Montessori and Reggio Emilia principles to foster social-emotional learning and executive function in young learners. Instead of demanding rigid compliance, educators prepare supportive environments and use practical activities, artistic expression, and collaborative projects to teach self-regulation. Children develop crucial skills like emotional literacy, perspective-taking, and problem-solving through guided practice and meaningful interactions rather than isolated lectures. Teachers carefully observe individual needs, document student progress, and adapt instruction to help children navigate challenges. Ultimately, the approach builds an inclusive classroom community where young learners can safely practice empathy, independence, and relationship repair.

The Joy Engine: Fidelity to the Child in Education

A full-stack, classroom-ready lesson for preschool, kindergarten, and early elementary learners

Core principle: Children do not develop emotional intelligence simply by being told to share, calm down, or make good choices. They need meaningful opportunities to practice emotional awareness, cooperation, problem-solving, independence, and self-regulation within a supportive community.

What if social-emotional learning (SEL) were not a 20-minute lesson squeezed between phonics and mathematics? What if the classroom itself became the curriculum for developing empathy, executive function, emotional literacy, and responsible independence?

Imagine children pouring water for a friend, negotiating how to build a bridge together, noticing that a classmate feels left out, repairing a structure after it collapses, and reflecting on what they might do differently tomorrow.

These are not interruptions to learning. They are opportunities to learn how to live, work, think, and create with other people.

A thoughtfully designed Montessori–Reggio Emilia-inspired classroom can bring these experiences together through practical life, purposeful play, artistic expression, collaborative inquiry, and explicit instruction in emotional and executive-function skills.

The goal is not a classroom filled with perfectly compliant children. It is a classroom community in which children gradually become more capable of understanding themselves, considering others, managing challenges, and participating meaningfully in shared work.


1. The educational foundation: Three systems working together

This lesson integrates three complementary educational frameworks.

Montessori: Independence, purposeful work, and self-regulation

Montessori environments emphasize prepared materials, meaningful choices, practical life, repetition, concentration, and increasing independence.

A child who carefully transfers water between pitchers is doing more than practicing coordination. The activity provides an opportunity to slow down, attend to a sequence, monitor movement, notice mistakes, and complete a purposeful task.

Practical life experiences can create natural opportunities to practice:

  • Sustained attention and concentration.

  • Following a sequence of steps.

  • Inhibiting an impulsive response.

  • Noticing and correcting mistakes.

  • Caring for shared materials and spaces.

  • Completing work and restoring the environment.

The teacher's role is to prepare the environment, demonstrate clearly, observe carefully, and provide only as much help as necessary.

Reggio Emilia: Relationships, inquiry, and the hundred languages

The Reggio Emilia Approach views children as capable participants in their own learning. Relationships, collaboration, the environment, artistic exploration, and documentation are central to its educational project. <sup><Link url="https://www.reggiochildren.it/en/reggio-emilia-approach" title="Reggio Children: The Reggio Emilia Approach"/></sup>

Children do not communicate their thinking through spoken language alone. They also think and express ideas through drawing, movement, music, dramatic play, construction, clay, and visual design.

For social-emotional learning, this matters enormously.

A child who cannot yet explain, “I felt frustrated because my idea was ignored,” might communicate that experience through a drawing, a puppet story, or a model of two characters trying to build together.

The teacher can use these representations to invite conversation rather than immediately supplying an interpretation.

Reggio-inspired practice encourages teachers to ask:

  • What is the child trying to understand?

  • What questions are emerging?

  • How are relationships influencing the investigation?

  • What can children show us through different forms of expression?

  • What should we offer next based on what we observe?

Executive function: The skills that help children manage learning and life

Executive function refers to a group of cognitive processes that support goal-directed behavior. Three commonly discussed components are:

  1. Working memory: Holding information in mind while using it.

  2. Inhibitory control: Pausing or resisting an immediate response when needed.

  3. Cognitive flexibility: Shifting attention, strategies, or perspectives when circumstances change.

Planning, organizing, monitoring progress, and regulating emotions draw on these and related skills.

The Harvard Center on the Developing Child explains that executive-function and self-regulation skills develop through experience, practice, supportive relationships, and appropriately scaffolded challenges. <sup><Link url="https://developingchild.harvard.edu/resources/handouts-tools/activities-guide-enhancing-and-practicing-executive-function-skills/" title="Harvard Center on the Developing Child: Activities Guide"/></sup>

The instructional implication: We should not simply demand self-control from young children. We should design experiences in which children can practice it with adult support, then gradually transfer more responsibility to them.

Learning objectives

By the end of the lesson, children will have opportunities to:

Social-emotional intelligence

  • Identify and communicate a range of emotions.

  • Recognize that different people may experience the same situation differently.

  • Practice listening, turn-taking, perspective-taking, and empathy.

  • Use language or other communication methods to express needs.

  • Practice resolving manageable disagreements.

Executive function

  • Remember and complete a short sequence of steps.

  • Pause before acting during a structured game.

  • Sustain attention to a self-chosen task.

  • Try an alternative strategy when the first one fails.

  • Plan, organize, and clean up materials.

  • Reflect on a choice and identify a possible next step.

Community participation

  • Contribute an idea to a shared project.

  • Respect another person's contribution.

  • Take responsibility for a classroom task.

  • Recognize that mistakes can be repaired and relationships can be strengthened.

These are practice goals, not expectations that every child will master every skill in one lesson.


3. Prepare the environment: The classroom is the third teacher

Before the children arrive, organize the space to communicate calm, agency, belonging, and purpose.

A Reggio-inspired environment can invite investigation, while Montessori-inspired organization makes materials accessible and encourages children to manage their own work.

Suggested learning areas

The Peace and Reflection Corner

Provide a comfortable seat, emotion cards, a small mirror, paper, crayons, and a few familiar calming tools.

This is a voluntary place to pause, reconnect, and seek support. It should never be used as a punishment or a place where a child is isolated against their will.

The Practical Life Studio

Arrange trays with manageable tasks such as transferring large objects with tongs, folding cloths, sorting classroom materials, or pouring water into sturdy containers.

Use age-appropriate, nontoxic materials and supervise activities involving water, small objects, or other potential hazards.

The Atelier

Offer drawing materials, recycled cardboard, clay or play dough, fabric scraps, blocks, and loose parts suitable for the children's ages.

The invitation is to represent an idea, feeling, relationship, or possible solution in more than one way.

The Collaboration Studio

Provide blocks, recycled construction materials, paper, tape, and simple planning sheets.

Children will work together to design a classroom where people can participate, ask for help, solve problems, and find a place to belong.

The Community Circle

Arrange seating so children can see one another without requiring every child to sit in a particular position. Some children may participate more comfortably while standing, holding an object, or sitting nearby.

The teacher's preparation checklist

  • Prepare a visual schedule.

  • Place materials where children can reach them independently.

  • Prepare emotion and problem-solving picture cards.

  • Create a small set of predictable classroom routines.

  • Plan a movement break.

  • Prepare an observation sheet.

  • Anticipate communication, sensory, mobility, and accessibility needs.

The environment should reduce unnecessary demands on children's working memory and self-control. A clear routine, visible materials, and predictable transitions make it easier for children to devote attention to the learning itself.


4. The scripted lesson

Part A — Welcome and emotional check-in

Time: 10 minutes

Primary skills: Emotional vocabulary, self-awareness, listening, and working memory.

Invite children to gather in the community circle.

Teacher says:

“Today we are going to investigate something important. We know how to build with blocks, paint pictures, count objects, and learn new words. But how do we build a classroom where people can learn together, even when they feel different things or have different ideas?”

Pause and allow children to respond.

“Every person has feelings. Sometimes we feel excited. Sometimes we feel worried, disappointed, proud, frustrated, or calm. Feelings give us information. We can learn to notice them and decide what to do next.”

Show three or four emotion cards or drawings.

Ask:

  • “What might this person be feeling?”

  • “What clues do you notice?”

  • “Could two people feel differently about the same event?”

  • “What helps you when a feeling becomes very big?”

Accept verbal responses, gestures, pointing, drawing, communication devices, or other meaningful forms of expression.

Teacher models:

“I might feel frustrated when my tower falls down. I can notice that feeling, take a breath if that helps me, and decide whether to try again, ask for help, or make a different plan.”

Do not insist that every child publicly share a personal feeling. Children can discuss a fictional character instead.

Executive-function connection: Children practice holding a question in mind, attending to another speaker, retrieving vocabulary, and considering more than one possible interpretation.

Montessori connection: Children participate at their own pace and gradually take responsibility for identifying and communicating their needs.

Reggio connection: Children construct meaning together through conversation, observation, and multiple forms of expression.

Part B — The practical life lesson: Slow hands, thoughtful minds

Time: 10–12 minutes

Primary skills: Inhibitory control, sustained attention, sequencing, and independence.

Invite children to select a practical life tray.

Possible tasks include:

  • Transferring large pom-poms with tongs.

  • Folding a small cloth.

  • Pouring water between small pitchers over a tray.

  • Sorting classroom materials into labeled containers.

  • Preparing a small arrangement of flowers with appropriate tools and supervision.

Demonstrate one task slowly, with minimal unnecessary talking.

Teacher says:

“First, watch my hands. I am going to take the tray, carry it carefully, complete the work, check what I have done, and return everything to its place.”

Demonstrate the sequence.

“Now it is your turn. You may choose one tray. Work carefully. If something goes wrong, pause and decide what you might try next.”

Avoid turning the task into a speed competition.

As children work, observe without interrupting every small mistake.

If a child spills water, say:

“The water spilled. What could help us take care of it?”

Allow the child to retrieve a cloth and participate in cleaning up.

If a child becomes frustrated, offer a choice:

“Would you like to try again, watch my demonstration, or choose another activity?”

Executive-function connection: Children practice attention, motor planning, sequencing, response inhibition, and monitoring their own work.

Important distinction: A practical life activity creates opportunities to practice executive-function skills; it is not a diagnostic test, and success on one task does not establish a general level of self-regulation.

Part C — The movement game: Freeze, notice, choose

Time: 5–7 minutes

Primary skills: Inhibitory control, listening, attention shifting, and flexible responding.

Invite children to stand, sit, or move in whatever accessible way works for them.

Explain the game:

“When the music plays, we move. When the music stops, we pause. We notice our bodies, listen for the next direction, and choose our next movement.”

Use a simple sequence:

  1. Move when the music plays.

  2. Pause when it stops.

  3. Copy a slow movement.

  4. Switch to a different movement when the teacher gives a new cue.

  5. Return to a comfortable resting position.

Teacher says:

“Sometimes our bodies want to keep moving even when the direction changes. We are practicing noticing the signal and choosing what to do next. Everyone is learning; mistakes are part of the game.”

Use short rounds. Avoid eliminating children for mistakes.

For children who find sound or unpredictable stopping difficult, offer visual signals, a predictable rhythm, or a quieter version.

Reflection questions:

  • “What helped you notice when the signal changed?”

  • “Was it easy or difficult to pause?”

  • “What did you do when you missed a signal?”

Explain that the goal is not perfect stillness. The goal is to practice noticing, adjusting, and trying again.

Part D — The social problem-solving story

Time: 10 minutes

Primary skills: Perspective-taking, emotional literacy, language, and flexible thinking.

Present this short story.

The Tower That Belonged to Everyone

Maya and Leo are building a tall tower. Maya wants to make it taller. Leo wants to add a bridge.

Maya reaches for the blocks and says, “I want the tall part!”

Leo pulls the blocks toward himself. “No! I was using those!”

The tower falls.

Maya looks disappointed. Leo feels angry. Neither child knows what to do next.

Ask the group:

  • “What might Maya be feeling?”

  • “What might Leo be feeling?”

  • “What happened just before the tower fell?”

  • “What does each child want?”

  • “How could they solve the problem without someone having to lose?”

Invite children to act out possible solutions with puppets or drawings.

Model several approaches:

Option 1: State the problem and make a request.

“I wanted to use those blocks. Can we make a plan?”

Option 2: Take turns.

“You can build the bridge first, and then we can work on the tall tower.”

Option 3: Combine ideas.

“Could we build a tall tower with a bridge?”

Option 4: Ask for help.

“We both have ideas. Can you help us figure out a plan?”

Teacher says:

“We can feel angry or disappointed and still work toward a safe solution. Feelings are allowed. Hurting people is not. When we have a problem, we can pause, explain what we need, listen, and look for a solution.”

Do not insist that children immediately forgive, hug, or agree. Genuine repair may require time, safety, and adult support.

Teacher's key move: Ask questions that help children think rather than simply telling them the correct answer.

If a child says, “Leo is bad,” respond:

“Let's look at what Leo did. Was the action helpful? What could he do differently? People can make mistakes and learn another way.”

This separates the child’s identity from the behavior and keeps the door open for growth.

Part E — The Reggio-inspired atelier: Make belonging visible

Time: 15–20 minutes

Primary skills: Collaboration, flexible thinking, planning, communication, and creative problem-solving.

Introduce the central project.

Teacher says:

“We have been talking about how people feel, how we solve problems, and how we work together. Now we have a challenge: Can we design a classroom community where everyone can learn, feel welcome, and get help when they need it?”

Invite children to choose a medium:

  • Draw a picture of a welcoming classroom.

  • Build a model using blocks and recycled materials.

  • Create a puppet scene showing someone helping a friend.

  • Use clay or play dough to represent a place where people feel safe.

  • Make a collaborative mural with pictures of helpful actions.

  • Dictate an idea for the teacher to write down.

Children may work individually, in pairs, or in small groups.

Introduce a simple planning routine

Write or display four picture-supported steps:

  1. Imagine: What would help people belong?

  2. Plan: What materials or ideas do we need?

  3. Create: Let's build, draw, or make it.

  4. Reflect: What worked? What might we change?

Model the process with a small example.

“I imagine a place where someone can go when they need a quiet moment. I plan to use a drawing and some blocks. I will make the space, then check whether it shows what I intended.”

Ask children to explain their own plans before beginning, using whatever communication method is accessible to them.

The teacher's role during the atelier

Observe the children's ideas and interactions.

Instead of saying, “That's wrong; do it this way,” ask:

  • “Tell me about your idea.”

  • “What are you trying to make happen?”

  • “What do you notice?”

  • “What could you change?”

  • “How will you decide whose idea to try first?”

  • “What could you do if you disagree?”

Record brief quotations when possible.

For example:

Child: “We need a place where people can go when it gets too noisy.”

Possible teacher note: The child is considering sensory needs and how the environment can support participation.

Do not assume a child's motivation from a single comment. Treat interpretations as hypotheses to explore through further observation and conversation.

The executive-function challenge

Introduce a change after the children have begun.

For example:

“The bridge is not staying up. What could we try?”

Or:

“We have fewer blocks than we expected. How can we change our plan?”

This is not a trick. It is an opportunity to practice flexibility.

Support children in naming the problem, considering options, testing an idea, and evaluating what happened.

If frustration escalates, reduce the difficulty, offer help, or provide a break. The objective is productive practice, not endurance of overwhelming stress.

Part F — Cooperative challenge: Build something together

Time: 10 minutes

Primary skills: Shared planning, working memory, turn-taking, negotiation, and cognitive flexibility.

Invite pairs or small groups to build a bridge, tower, shelter, or other structure.

Give each group a manageable supply of blocks and a simple goal.

For example:

“Work together to build a bridge that can hold a small toy. Before you begin, each person will share one idea.”

Provide a visual sequence:

  • Listen to each person's idea.

  • Decide what to try first.

  • Build and test.

  • Change the plan if needed.

  • Put the materials away together.

The structure does not need to succeed on the first attempt.

If children disagree, use a neutral prompt:

“I hear two different ideas. Let's pause. What is each person trying to do? What could we test first?”

Children may take turns testing competing ideas rather than reaching an immediate verbal agreement.

If one child dominates, offer roles such as builder, materials manager, tester, or documentarian. Rotate roles over time so that each child can practice different responsibilities.

Avoid assigning permanent roles based on perceived ability or temperament.

Reflection questions:

  • “What did your group try first?”

  • “Did you change your plan?”

  • “How did you make room for another person's idea?”

  • “What would you do differently next time?”

Part G — The peace table: Repair, not punishment

Time: 5–8 minutes

Primary skills: Emotional regulation, communication, accountability, and relationship repair.

Introduce a simple, optional conflict-resolution routine that an adult can facilitate.

Step 1: Pause and establish safety.

“Let's make sure everyone is safe. We can take a moment before we talk.”

Step 2: Listen to each perspective.

“Tell me what happened from your point of view.”

Give each child time to speak or communicate in their own way.

Step 3: Identify needs and impact.

“What were you hoping would happen?”

“How did this affect the other person?”

Step 4: Consider possible solutions.

“What could help make things better?”

Step 5: Agree on a realistic next step.

“Would you like to rebuild together, return the material, give each other space, or ask for help?”

The teacher remains responsible for safety and fair participation. Children should not be expected to negotiate alone when there is aggression, coercion, a significant power imbalance, or a repeated pattern of harm.

For very young children, adults may need to supply much of the language and structure. The child can still participate through gestures, choices, and small acts of repair.

A crucial principle: Accountability should help children understand impact and learn safer alternatives. Shame, forced apologies, and public humiliation are not necessary for learning.

Part H — Closing reflection and community commitment

Time: 5 minutes

Gather the group near the children's work.

Invite each child to complete one prompt, orally, through drawing, or by selecting a picture.

  • “Today I practiced…”

  • “When something was difficult, I…”

  • “One way I helped our community was…”

  • “Next time, I want to try…”

  • “Something I learned about another person was…”

The teacher may model an honest reflection:

“I noticed that I wanted to solve the problem quickly. I practiced slowing down and listening to your ideas first.”

Invite the children to choose one shared commitment for the coming week.

Examples:

  • We ask before taking another person's work.

  • We make room for different ideas.

  • We help repair mistakes.

  • We ask for help when a problem feels too big.

  • We care for our shared materials.

Display the children's words and artwork where they can revisit them.

End with this message:

“We are a community of learners. We do not have to know everything today. We practice, make mistakes, ask for help, and learn new ways to care for ourselves and one another.”


5. The executive-function skill map

The purpose of this integrated lesson is to connect observable classroom experiences to the skills children are practicing.

ActivityExecutive-function practiceSocial-emotional connection
Emotion check-inAttention and working memoryIdentifying feelings
Practical life traySequencing and response inhibitionPatience and independence
Movement gameInhibitory control and shifting attentionManaging impulses
Social problem storyWorking memory and flexible thinkingPerspective-taking
Atelier projectPlanning and monitoringExpressing ideas and negotiating
Cooperative constructionFlexible problem-solvingCollaboration and listening
Peace tableReflecting before respondingRepairing relationships
Closing reflectionRecall and self-monitoringSelf-awareness and accountability

These skills overlap. A child may be practicing several at once, and the same activity can present very different demands for different learners.

A child who is quiet is not necessarily more regulated than a child who moves frequently. A child who follows directions immediately is not necessarily more empathetic than a child who needs additional time to respond.

Observe the actual skill, not the appearance of compliance.


6. Differentiation: Following the child

A child-centered approach does not mean every child receives an identical activity. It means that the teacher observes the child's current capacities, interests, needs, and barriers, then adjusts instruction to make meaningful participation possible.

For children who need more support

  • Reduce a multi-step task to one or two steps.

  • Use picture schedules and first–then prompts.

  • Offer two concrete choices instead of a broad, open-ended question.

  • Model a short phrase such as “Help, please” or “My turn next.”

  • Use puppets to rehearse a social situation before asking children to navigate it with peers.

  • Provide a predictable transition warning.

  • Offer movement, sensory adjustments, or a quieter workspace.

  • Allow additional processing time before repeating a question.

  • Break collaborative projects into manageable roles.

For children who are developing language skills

Teach short, functional phrases:

  • “I need help.”

  • “Stop, please.”

  • “Can I have a turn?”

  • “I have another idea.”

  • “Let's try again.”

  • “I need a break.”

Pair spoken language with visuals, gestures, signs, or augmentative and alternative communication when appropriate.

For children who experience strong emotions

Do not treat emotional intensity as deliberate defiance by default.

First consider safety, sensory demands, communication difficulties, fatigue, transitions, task difficulty, and the child's available regulation strategies.

Use calm, concise language:

“I can see this is difficult. I'm here to help. Let's make the next step smaller.”

Teach regulation strategies when the child is calm, and practice them during manageable challenges.

For children ready for additional complexity

Invite them to:

  • Design a visual guide for solving group problems.

  • Compare two different solutions to a shared challenge.

  • Explain why a plan changed.

  • Create a puppet play showing conflicting perspectives.

  • Interview classmates about what makes a classroom welcoming.

  • Develop a class project that responds to an observed need.

More advanced work should deepen thinking and responsibility rather than simply increase the volume of assignments.

For children with dyslexia, dysgraphia, ADHD, autism, or other learning differences

Offer multiple ways to access information and demonstrate understanding. Use oral language, visual supports, manipulatives, movement, drawing, and assistive technology as appropriate.

Do not require a child to write a reflection if writing difficulty prevents the child from expressing the underlying idea. Conversely, do not assume that every child with a particular diagnosis requires the same support.

The guiding question remains:

What is the child trying to communicate or accomplish, and what support will help the child participate meaningfully?


7. Observation and assessment: Make learning visible

Social-emotional development is complex. A single lesson cannot establish a child's emotional intelligence, diagnose an executive-function difficulty, or predict future behavior.

Teachers can, however, document specific behaviors, the support provided, and how the child responds over time.

Use the following observation tool during the lesson.

SkillObservable evidence
Emotional communicationIdentifies a feeling, signals a need, or uses a supported communication method
ListeningAttends to another person's contribution in an accessible way
Working memoryUses a visual or verbal sequence to continue a task
Inhibitory controlPauses or changes an action with developmentally appropriate support
FlexibilityTries an alternative after a problem occurs
PlanningIdentifies a next step before or during a task
CooperationContributes to shared work and responds to another person's idea
RepairParticipates in an appropriate action to address a mistake or conflict

A simple observation scale

Use this as a local instructional record, not a standardized assessment.

  • Observed independently: Demonstrated in this context without a direct prompt.

  • Observed with support: Demonstrated with modeling, a visual, a reminder, or adult guidance.

  • Not yet observed: The opportunity did not produce observable evidence of the skill.

  • Not assessed: There was no suitable opportunity to observe the skill.

Avoid interpreting “not yet observed” as inability. A child may need a different task, more time, a more familiar adult, or a different way to communicate.

Example of meaningful documentation

Less useful note: “Doesn't share.”

More useful note: “During block construction, the child held the materials when a peer requested a turn. After the teacher modeled a turn-taking phrase and offered a visual timer, the child agreed to a short turn and resumed building.”

The second observation tells us what happened, what support was effective, and what the teacher might try next.

Follow the child over time

Record observations across multiple settings:

  • Independent practical life.

  • Outdoor play.

  • Collaborative construction.

  • Story discussion.

  • Transitions.

  • Conflict-resolution opportunities.

  • Child-initiated projects.

Patterns across contexts are more informative than one isolated event.

Reggio-inspired pedagogical documentation can bring together children's words, photographs of their work, drawings, teacher observations, and follow-up questions. The aim is to make the learning process visible and use that understanding to plan what comes next.

For a useful reference, see <Link url="https://www.reggiochildren.it/en/reggio-emilia-approach" title="Reggio Children’s description of its educational approach"/>.


8. Family connection: Build continuity between home and school

Social-emotional learning becomes more meaningful when children encounter compatible language and routines across their daily environments.

Send home one simple question each day rather than a packet of worksheets.

Monday: What was something you found difficult today?

Tuesday: How did you ask for help?

Wednesday: What did you do when someone had a different idea?

Thursday: What is one thing you can do to help care for our home or classroom?

Friday: What is something you are proud of learning this week?

Families can answer these questions through conversation, drawing, play, or a shared practical task.

Invite families to share songs, stories, home languages, traditions, and examples of cooperation that are meaningful in their households. Avoid suggesting that every family must use the same emotional vocabulary or conflict-resolution style.

The purpose is to create a partnership in which children are supported in communicating needs, developing independence, and participating in relationships.


9. Extending the lesson across five days

Rather than treating social-emotional learning as a single event, use the central project to create a short inquiry.

DayFocusInvestigation
1Emotional awarenessHow do we recognize and communicate feelings?
2IndependenceWhat helps us complete work and care for our environment?
3Empathy and perspectiveHow might different people experience the same situation?
4Collaboration and flexibilityHow can we work through a problem together?
5Community and reflectionWhat have we learned about creating a welcoming classroom?

Revisit the children's original drawings and ideas. Ask what has changed and what they now understand differently.

The teacher can introduce new materials or questions in response to the children's investigations. One group's interest in quiet spaces might lead to a study of sound, architecture, and sensory environments. Another group's interest in friendship might lead to puppet theater, storytelling, and collaborative writing.

This is where the approaches complement one another: purposeful routines provide structure, while inquiry and artistic exploration allow the learning to evolve.


10. What the research supports—and what it does not establish

Executive function and self-regulation are important areas of child development. Harvard's Center on the Developing Child provides age-appropriate activities for practicing attention, working memory, and self-control through everyday interactions and play.

Its resource, <Link url="https://developingchild.harvard.edu/resources/handouts-tools/brainbuildingthroughplay/" title="Brain-Building Through Play"/>, offers examples of playful experiences that provide opportunities to practice these skills.

The Reggio Emilia educational project emphasizes relationships, the learning environment, the atelier, family participation, and documentation. Its official description is available at <Link url="https://www.reggiochildren.it/en/reggio-emilia-approach" title="Reggio Children"/>.

These sources support the value of designing rich environments and giving children opportunities to practice developing skills. They do not establish that this exact combined lesson, or Montessori–Reggio integration by itself, will produce a particular improvement in executive function or social-emotional outcomes.

The lesson should therefore be treated as a developmentally informed instructional design, evaluated through observation and adapted to the children who participate.


11. The Joy Engine connection: Fidelity to the child

A common mistake in education is to turn every important developmental goal into a compliance program.

We tell children to sit still, pay attention, share, follow directions, use their words, and manage their emotions. Yet we do not always provide the time, environment, modeling, or guided practice needed to develop those abilities.

A child-centered classroom takes a different approach.

Instead of asking only, “Why won't this child behave?” the teacher asks:

  • Is the task accessible?

  • Does the child understand what is expected?

  • Can the child communicate the problem?

  • Is the environment contributing to the difficulty?

  • What skill is the child being asked to use?

  • What support would make that skill more accessible?

  • What can we observe to determine whether the support is helping?

This is not an argument against structure, expectations, or explicit instruction. Children need all three.

It is an argument for making structure serve development rather than demanding that development conform to a rigid structure.

Montessori reminds us to prepare the environment and protect meaningful independence. Reggio Emilia reminds us to listen to children's ideas and make their thinking visible. Executive-function research reminds us that attention, working memory, and self-regulation develop through practice and support.

Together, these ideas suggest a practical educational commitment:

Teach the skill. Prepare the environment. Observe the child. Adjust the support. Try again.

A child who struggles to share may need help with turn-taking language, waiting, or negotiating access to materials. A child who abandons a difficult project may need the task broken into smaller steps. A child who reacts strongly to noise may need environmental adjustments rather than another lecture about self-control.

The intervention should respond to the observed need.

That is fidelity to the child.

Conclusion: Build the human capacities that make learning possible

Social-emotional intelligence and executive function are not decorative additions to academic learning. They influence how children participate in shared activities, manage challenges, communicate needs, and pursue goals.

But children do not need to master every social skill before they can belong to a classroom community. They belong while they are learning.

A Montessori–Reggio Emilia-inspired environment can provide meaningful opportunities to practice independence, emotional communication, flexible thinking, cooperation, and repair. The teacher's responsibility is to make those opportunities accessible, observe what happens, and respond to the child rather than simply repeating a demand.

At Reading Sage, the larger goal is not to produce children who never become frustrated or disagree with one another.

It is to help children become increasingly capable of noticing what is happening, asking for help, trying a new strategy, considering another perspective, and participating in a community.

That is the work of education beyond the worksheet.

That is the work of the Joy Engine.

Reading Sage | Sean Taylor, M.Ed.

Follow the child. Teach the skill. Build the community. Keep the joy in learning.

In early childhood social-emotional learning (SEL), executive function provides the core cognitive framework that allows children to regulate their emotions, direct their attention, and participate constructively in a community. Rather than viewing SEL as separate from cognitive development, executive function skills serve as the building blocks for managing behavior and navigating social interactions.

Executive function relies on three primary components that directly support social-emotional growth:

  • Inhibitory Control (Self-Control & Pause): Inhibitory control enables a child to pause and resist an immediate, impulsive reaction. In a social setting, this allows children to manage strong emotional responses, wait for a turn, stay focused during group activities, and follow predictable classroom routines.
  • Working Memory (Emotional Awareness & Reflection): Working memory involves holding information in mind while actively applying it. It helps children remember classroom agreements, hold multi-step instructions, retrieve emotional vocabulary when describing how they feel, and keep a peer's perspective in mind during a conversation.
  • Cognitive Flexibility (Perspective-Taking & Problem-Solving): Cognitive flexibility allows children to shift strategies, adjust to changes, and see situations from multiple viewpoints. In SEL, this skill is essential for negotiating shared work, adapting when a plan fails (such as a collaborative block tower collapsing), and finding fair solutions during conflicts.

Scaffolding Regulation and Problem-Solving

Because young children are still developing these cognitive processes, the research emphasizes that adults should not simply demand self-control; instead, educators must design structured environments and experiences where children can actively practice these skills.

For example:

  • Reducing Cognitive Load: Well-organized environments and clear routines lower unnecessary demands on working memory, allowing children to focus their energy on emotional regulation and peer interactions.
  • Targeted Practice Tasks: Purposeful activities—such as practical life sequencing exercises, movement games with stop/start cues, cooperative building challenges, and conflict-resolution routines (like a "peace table")—give children structured opportunities to practice attention shifting, planning, and relationship repair.

Executive function and social-emotional skills overlap continuously. Together, they build the internal capacities children need to understand their own feelings, consider the needs of others, handle setbacks, and collaborate effectively

In early childhood classrooms, practical life activities—such as pouring water between pitchers, folding cloths, using tongs, or sorting materials—build self-regulation by providing tangible, hands-on opportunities to practice core executive function skills[1][2]. Rather than demanding self-control abstractly, these activities allow children to develop internal regulation through purposeful, structured work[1].

Specifically, practical life activities strengthen self-regulation across several key developmental areas:

  • Inhibitory Control: Executing fine-motor tasks requires children to slow down, control impulsive physical movements, and move deliberately[2].
  • Sequencing and Working Memory: Tasks follow a predictable, multi-step sequence (e.g., carrying a tray carefully, carrying out the activity, checking the result, and returning materials to their proper place)[1]. Following this process strengthens motor planning and working memory[4][5].
  • Sustained Attention and Concentration: Working through an entire activity cycle requires children to focus their attention and stay engaged from start to finish[1].
  • Self-Monitoring and Error Correction: Practical life tasks make mistakes immediately visible[1][5]. For example, if water spills while pouring, the child is prompted to pause, notice the error, and take active responsibility for repairing it by fetching a cloth[1][4]. This teaches self-monitoring and problem-solving without triggering shame or dysregulation[1].
  • Independence and Restoration: Completing a purposeful task and restoring the environment fosters autonomy, patience, and personal responsibility[1].

By embedding cognitive control within meaningful physical tasks, practical life activities lower unnecessary cognitive load and give children structured, everyday practice in guiding their own behavior[1]

The "Freeze, Notice, Choose" movement game is a 5–7 minute classroom activity designed to build inhibitory control, attention shifting, and impulse management through playful movement[1][2]. Rather than requiring rigid compliance or perfect stillness, the game helps children practice pausing, noticing cues, and consciously choosing their next action[1][3].


How the Game Works

  1. Move (Music Plays): Children stand, sit, or move in whatever accessible way works for them while music plays[1].
  2. Freeze / Pause (Music Stops): When the music stops, children immediately pause their physical movement[1].
  3. Notice: Children take a moment to notice their bodies, pay attention to physical signals, and listen for the next instruction[1].
  4. Choose (Switch Movement): When the teacher gives a new cue, children choose and execute a new movement—such as copying a slow gesture or switching to a different motion—before returning to a resting position[1][4].

Key Facilitation Principles

  • Non-Competitive Environment: The game uses short rounds and avoids eliminating children for mistakes[4]. Mistakes are explicitly framed as a natural part of learning[4].
  • Adult Framing: The teacher models reflection by explaining, *"Sometimes our bodies want to keep moving even when the direction changes. We are practicing noticing the signal and choosing what to do next"*[4].
  • Accessibility Adaptations: For children who find sudden stops or unpredictable audio overwhelming, educators can provide visual signals, a predictable rhythm, or a quieter environment[4].

Executive Function & SEL Connection

  • Executive Function Skills: It directly exercises inhibitory control (stopping an immediate physical impulse) and shifting attention (listening for new cues and changing tasks)[1][2].
  • Reflection & Metacognition: After playing, the teacher invites children to reflect with questions such as:
    • *"What helped you notice when the signal changed?"*[4]
    • *"Was it easy or difficult to pause?"*[3]
    • "What did you do when you missed a signal?"

Autism, Baby Teeth, and Environmental Chemicals Research Review

Baby Teeth, Environmental Chemicals, and Autism: What Does the Research Really Tell Us?

Recent scientific literature evaluates a pilot case-control study exploring the connection between environmental chemicals and autism spectrum disorder through the analysis of shed baby teeth. While researchers detected higher concentrations of various substances like plasticizers and pesticides in the dental tissues of autistic children, experts emphasize that this small observational study only shows an association rather than definitive causation. The texts explain how primary teeth serve as valuable biological archives of early life exposure, yet caution against jumping to conclusions due to methodological limitations and small sample sizes. Ultimately, the reviews urge parents and educators to focus on reasonable precautionary steps to reduce hazard exposures without creating unnecessary fear, blaming families, or misinterpreting neurodiversity.












A Reading Sage Literature Review on Early-Life Chemical Exposure, Developmental Neuroscience, and the Limits of a Small Pilot Study

By Sean Taylor, M.Ed. | Reading Sage

Introduction: What Can a Baby Tooth Tell Us About Early Childhood Development?

A child's shed baby tooth may look like an ordinary childhood keepsake. To an environmental health researcher, however, it can serve as a remarkable biological archive.

As primary teeth develop during pregnancy and early childhood, some substances circulating in the body can become incorporated into dental tissues. Researchers can analyze these tissues years later to investigate aspects of a child's earlier environmental exposures. Unlike a single blood or urine sample, which typically reflects a more limited period, a developing tooth can preserve evidence of exposure across a longer developmental window.

This approach has become particularly relevant to research into autism spectrum disorder (ASD), a complex neurodevelopmental condition influenced by multiple genetic and developmental factors.

In August 2026, researchers affiliated with the University of Texas at San Antonio published a pilot case-control study titled A Pilot Autism Case-Control Study of Pesticides and Plasticizers in Shed Baby Teeth in the journal Neurotoxicology and Teratology. The findings attracted attention because researchers detected higher concentrations of most of the chemicals examined in teeth from children with autism than in teeth from typically developing children.

The study raises important questions about early-life exposure to pesticides, plasticizers, flame-retardant-related compounds, fragrance ingredients, and other substances found in everyday environments.

But an important scientific distinction must guide the discussion:

An association between chemical concentrations and autism is not proof that the chemicals caused autism.

The results are a reason to investigate environmental exposures more carefully—not a reason to blame parents, stigmatize autistic children, or conclude that ordinary household products have been shown to cause autism.

This literature review examines the study, the science of tooth-based exposure biomarkers, the broader environmental-health literature, the limitations of current evidence, and practical implications for parents, teachers, and early-childhood professionals.

1. The 2026 UT San Antonio Study: What Did Researchers Find?

The study by Lynne P. Heilbrun and colleagues examined shed primary teeth donated by families of 38 children. The sample included 22 children with autism and 16 typically developing controls.

Researchers used two-dimensional gas chromatography coupled with time-of-flight mass spectrometry, an analytical technique that can identify and measure numerous chemical compounds within complex samples.

Rather than testing only a small, predetermined list of chemicals, the researchers used a broad analytical approach to investigate chemical exposure patterns.

Key findings

FindingWhat the researchers reported
Participants38 children: 22 with autism and 16 controls
Compounds examined in the main comparison60 compounds detected in more than half of participants
Compounds with higher concentrations in the autism group57 of 60, or 95%
Compounds significantly higher in the autism group19 of 60
Compounds classified as developmental toxicants or endocrine disruptors39 of 60
Compounds lacking EPA developmental-toxicity data21 of 60
Notable potential exposure sourcesBaby-product materials, food-contact materials, PEX tubing, fragrances, and flame-retardant-related products

Source: Heilbrun et al., 2026, Neurotoxicology and Teratology. DOI: 10.1016/j.ntt.2026.107710.

The distinction between the 57 compounds with higher measured concentrations and the 19 statistically significant differences is important. The first figure describes the direction of the observed differences; the second identifies the subset meeting the study's statistical significance threshold.

The findings suggest a possible difference in early-life chemical exposure profiles between the two groups. They do not demonstrate that every compound was harmful at the measured concentration, nor that every child with autism experienced the same exposures.

Why the results deserve attention

The study's significance lies partly in its examination of multiple chemicals together. Children do not encounter environmental substances one at a time in carefully controlled laboratory conditions. They live in environments containing mixtures of substances from food, air, water, household products, building materials, and personal care products.

Researchers need better methods to understand these combined exposure patterns, particularly during periods of rapid development.

Nevertheless, this was a small exploratory study. Its findings should be interpreted as preliminary evidence requiring replication, not as a definitive explanation for autism.

2. Baby Teeth as Biological Archives: The Science of Exposure Biomarkers

One of the most interesting aspects of this research is its use of deciduous teeth as biological exposure records.

Primary teeth begin developing before birth. Different teeth form and mineralize on different schedules, with development continuing into early childhood. During this process, certain substances or their metabolites can become incorporated into dental tissues.

After the tooth is shed, researchers can examine those retained chemical signatures.

How this differs from blood and urine testing

Blood and urine testing remain valuable tools for measuring chemical exposure. However, many substances are metabolized and eliminated relatively quickly. A sample collected today may not reliably reconstruct exposure that occurred months or years earlier.

Tooth analysis offers a different perspective:

  • Blood and urine: Often provide information about relatively recent exposure, depending on the substance and test.

  • Baby teeth: Can preserve information about certain exposures during the period when the tooth formed.

  • Repeated or time-resolved measurements: When validated methods are available, these may help researchers distinguish exposure patterns across developmental periods.

A tooth is not a perfect chemical diary. The substances that can be detected depend on the analytical method, their chemical properties, the tissue examined, and how the tooth was collected and processed. Some measurements may reflect exposure over a broad period rather than identify a precise day or month.

The researchers' description of teeth as a long-term exposure record is therefore useful, provided we do not interpret it as a complete record of every chemical a child encountered.

Why timing matters in developmental research

Prenatal and early-childhood development involve rapid changes in the brain, nervous system, immune system, and endocrine system. Environmental-health researchers investigate whether exposure to particular substances during sensitive developmental periods can alter biological processes.

A tooth-based biomarker can help researchers ask more precise questions about timing and exposure. It cannot, by itself, establish what happened in the brain or whether a particular exposure caused a later developmental outcome.

That distinction is central to interpreting this study responsibly.

3. Which Chemical Groups Were Identified?

The 2026 investigation examined compounds associated with several broad categories of products and environmental sources. These categories are not interchangeable: chemicals within the same category can have very different properties, exposure levels, and toxicological profiles.

A. Phthalates and other plasticizers

Plasticizers are substances added to some materials to change flexibility, durability, or other physical properties. Phthalates are one group of plasticizers, although not all plasticizers are phthalates.

Some phthalates have been investigated for their potential to interfere with endocrine signaling and affect reproductive or developmental processes. Research has also examined associations between prenatal exposure to certain phthalates and childhood neurodevelopmental outcomes.

However, evidence varies by individual chemical, exposure level, developmental window, and outcome measured. An association involving one phthalate cannot automatically be applied to every plasticizer or every plastic product.

B. Pesticides and related compounds

Certain pesticides are established toxicants, and some can affect the developing nervous system. The potential health effects depend on the particular compound, dose, route of exposure, and timing.

Observational research has investigated whether prenatal exposure to certain pesticides is associated with an increased likelihood of autism or other developmental differences. These studies contribute to an important research field, but they do not establish that all pesticides have the same effects or that pesticide exposure explains autism in an individual child.

C. Organophosphate esters and flame-retardant-related compounds

Organophosphate esters are a broad chemical group used in some flame retardants, plasticizers, and other applications. Some compounds in this group have attracted attention because of possible effects on neurodevelopment, hormones, or other biological systems.

Finding a compound associated with a product category does not necessarily identify the exact product from which a child was exposed. Several sources can contribute to exposure, and a chemical may have multiple uses.

D. Fragrance ingredients, preservatives, and other household chemicals

The study also identified compounds associated with fragrances, food preservatives, personal care products, and cleaning-product ingredients or their manufacturing processes.

The presence of a chemical in a fragrance or preservative does not establish that its use in every product is dangerous. Safety depends on the individual substance, concentration, route of exposure, and relevant toxicological evidence.

A further challenge is that chemical databases do not contain equally complete developmental-toxicity information for every compound. Missing data mean that uncertainty remains; they do not automatically establish that a substance is either safe or harmful.

E. Benzyl benzoate and baby-product materials

Benzyl benzoate was among the compounds receiving attention in media coverage because its measured concentration was substantially higher in the autism group.

The study and its accompanying reporting also identified compounds previously reported to migrate from baby-bottle components. Five of the nine compounds that best differentiated the groups were associated with migration from baby bottles.

These observations are scientifically interesting, but they do not prove that baby bottles were the source of the chemicals in any particular child's teeth. Similar compounds can occur in multiple products and environments, and the study was not a controlled experiment assigning children to different products.

The appropriate conclusion is that potential exposure pathways warrant further investigation.

4. What Does the Broader Scientific Literature Say?

The 2026 findings should not be evaluated in isolation. They belong to a broader body of research examining environmental exposures, early development, autism, and the usefulness of biological samples for reconstructing exposure histories.

A. Earlier research using primary teeth

Palmer's 2024 study, An Exploratory Investigation of Organic Chemicals Detected in Baby Teeth: Differences in Children with and without Autism, examined teeth from 22 children with autism and 20 typically developing children.

The researchers reported a higher average number of identified compounds in the autism group. Many of the chemicals belonged to categories such as plasticizers, pesticides, preservatives, and substances associated with fragranced products.

The study supports the feasibility of using primary teeth to investigate organic chemical exposure. It also shares important limitations with the newer research: small samples, observational comparisons, and uncertainty about why the groups differed.

The 2024 and 2026 investigations should be treated as separate studies rather than as interchangeable reports of the same sample. Their analytical approaches and study populations differ.

B. Earlier tooth studies of metals

Research has also used baby teeth to investigate exposure to metals, including lead, manganese, and zinc.

The National Institute of Environmental Health Sciences summarizes research comparing children with autism with their unaffected twins. Some studies have reported differences in the timing or levels of metal deposition in primary teeth.

This literature is relevant because it demonstrates how teeth can help researchers investigate developmental exposure patterns that may be difficult to reconstruct using a single blood sample.

However, metals and organic compounds are different chemical classes. Findings about lead, manganese, or zinc cannot be used as direct proof of a causal relationship between pesticides or plasticizers and autism.

C. Environmental exposure and neurodevelopment

The broader environmental-health literature has investigated several possible contributors to developmental outcomes, including particular pesticides, air pollutants, endocrine-disrupting chemicals, and certain metals.

The strength of evidence differs considerably across exposures. Some substances are established developmental hazards under particular conditions; evidence connecting a specific exposure to autism is often less conclusive.

It is important to distinguish three questions:

  1. Can a chemical affect a biological system under certain conditions?

  2. Is a particular exposure associated with a developmental outcome in human populations?

  3. Does that exposure cause the outcome, independently or in combination with other factors?

The answer to the first question does not automatically answer the second or third.

A chemical's ability to harm the nervous system at a particular dose is important toxicological information. It does not establish that the dose experienced by a particular child was sufficient to produce an effect, or that the effect would specifically be autism.

D. Genetic and environmental contributions

Autism is a heterogeneous neurodevelopmental condition with substantial genetic contributions and complex developmental pathways. Researchers continue to investigate how genetic susceptibility and environmental factors may interact.

A gene-environment interaction is a scientific hypothesis that some exposures may have different effects depending on an individual's genetic or biological characteristics. It is not evidence that the 2026 tooth study identified such an interaction.

To demonstrate one, researchers would need appropriate genetic information, reliable exposure measurements, adequately powered analyses, and independent replication.

The National Institute of Environmental Health Sciences provides a useful overview of current research on autism and environmental factors: https://www.niehs.nih.gov/health/topics/conditions/autism.

5. The Critical Question: Association or Causation?

The central scientific limitation of the 2026 study is that it compared chemical measurements in children with and without autism after their teeth had formed. It did not experimentally manipulate exposure, and it cannot establish that the measured differences preceded the developmental processes associated with autism.

Several explanations remain possible.

Hypothesis 1: Some exposures may contribute to developmental risk. Certain environmental substances may influence biological processes relevant to neurodevelopment. This possibility deserves careful investigation for individual chemicals and exposure levels.

Hypothesis 2: Children may differ in chemical metabolism or elimination. If individuals process particular substances differently, concentrations measured in biological tissues may differ even when their external exposures are similar. This is a hypothesis, not an established explanation for the findings.

Hypothesis 3: The groups may differ in exposure sources or circumstances. Diet, housing, geography, household products, occupational exposures affecting parents, and other factors can influence environmental exposure patterns.

Hypothesis 4: Multiple factors may contribute to the observed differences. Chemical mixtures, individual biological differences, socioeconomic circumstances, and other unmeasured variables may influence the results.

Hypothesis 5: Some differences may reflect chance or analytical uncertainty. When researchers compare many compounds in a small sample, the possibility of false-positive findings increases. Independent replication and appropriate statistical methods are essential.

These explanations are not mutually exclusive. The present study cannot determine which, if any, account for the observed pattern.

Why 19 statistically significant findings are not 19 proven causes

Statistical significance is a measure of how compatible observed data are with a specified statistical model. It does not establish causation, clinical importance, or the probability that a chemical caused autism.

When many compounds are tested, multiple-comparison issues become particularly important. Unless adequately addressed, testing many substances can increase the likelihood that some will appear statistically significant by chance.

The study's findings should therefore be viewed as a set of signals to investigate, rather than a list of 19 established autism-causing chemicals.

The size of a difference also needs careful interpretation. A large percentage difference between two groups can attract attention, but without adequate information about the absolute concentration, measurement uncertainty, toxicological threshold, and relevant exposure period, it cannot independently tell us whether a measured level was harmful.

6. What the Study Cannot Tell Us

A responsible review must make the limitations explicit.

First, the sample was small. Thirty-eight children are not enough to establish that the observed chemical patterns apply broadly to all autistic children or to different populations.

Second, the research was observational. It cannot show that exposure caused autism, and it cannot establish the direction of the relationship between the measured concentrations and the developmental outcome.

Third, the study did not identify the source of every chemical. Detecting a substance that can migrate from a baby bottle does not establish that a particular child used a bottle containing that substance or that the bottle was the source of the measured exposure.

Fourth, exposure measurements are not equivalent to measurements of harm. Detection establishes that a substance or chemical signature was present in the analyzed sample. It does not establish that the concentration caused injury or affected a child's development.

Fifth, the study does not identify an individual diagnostic test. Baby-tooth chemical analysis is a research method, not a validated clinical test for diagnosing autism, determining its cause, or guiding treatment.

Finally, the findings cannot be generalized to all plastics, pesticides, fragrances, or preservatives. Each compound requires its own evidence-based assessment.

These limitations do not make the study unimportant. They define what researchers need to do next.

7. Why This Research Matters to Parents and Educators

Environmental health is relevant to early childhood education because children grow and learn within physical environments that influence their health and well-being.

Teachers and parents can reasonably support efforts to reduce established environmental hazards, improve indoor air quality, prevent unsafe pesticide exposure, and ensure access to clean drinking water. Such measures benefit children's health without requiring claims that a specific chemical causes autism.

At the same time, educators should be careful not to interpret an autistic child's behavior, communication differences, sensory preferences, or learning profile as evidence of toxic exposure.

Autism is not a diagnosis that can be inferred from a child's behavior in a classroom, nor can it be attributed to a household product based on this research.

For Reading Sage, the educational implication is straightforward: developmental science should encourage better questions, more careful observation, and informed decision-making—not fear-based explanations of children's differences.

A practical, proportionate approach to reducing exposure

Families who want to reduce avoidable chemical exposures can consider reasonable precautions:

  • Follow public-health guidance for pesticide use, including label instructions and appropriate re-entry intervals.

  • Avoid heating food in containers not designed for that use, and follow the manufacturer's instructions for food-contact products.

  • Use fragrance-free personal care or cleaning products when preferred, particularly if fragrance causes irritation or symptoms.

  • Follow local drinking-water advisories and use appropriately certified treatment systems when testing identifies a problem.

  • Wash produce under running water and follow food-safety guidance rather than relying on unproven detoxification methods.

  • Ask healthcare professionals or public-health agencies about specific, credible exposure concerns instead of ordering unvalidated commercial toxin tests.

These steps are precautionary measures, not proven methods of preventing autism. Families should not feel compelled to discard every plastic item, purchase expensive specialty products, or undertake restrictive diets based on this pilot study.

Most importantly, parents should never be blamed for a child's autism because they used a particular bottle, lotion, food container, or household product. The research does not support that conclusion.

8. What Should Researchers Do Next?

The next stage of this research should move beyond identifying differences and begin testing explanations for them.

Priority 1: Replicate the findings in larger populations

Independent research teams should examine larger, more diverse groups of children. Replication would help determine whether the same chemicals and exposure patterns consistently differ between groups.

Priority 2: Improve the timing of exposure measurements

Researchers should use validated methods to determine which developmental periods the chemical signatures represent. When possible, tooth measurements could be combined with pregnancy records, repeated biological samples, and environmental monitoring.

Priority 3: Measure relevant confounding variables

Studies should collect information about diet, housing, geography, socioeconomic circumstances, parental occupational exposures, medication use, and other factors that could influence chemical exposure patterns.

These variables must be considered carefully rather than assuming that the chemical differences themselves explain the developmental outcome.

Priority 4: Improve chemical identification and toxicological assessment

Researchers should distinguish confirmed chemical identities from tentative analytical matches, report measurement uncertainty, and evaluate the biological relevance of measured concentrations.

They should also clarify when a compound has demonstrated developmental toxicity, when evidence is limited to laboratory studies, and when relevant data are missing.

Priority 5: Examine mixtures rather than isolated substances alone

Children encounter combinations of chemicals, and the effects of mixtures may differ from those of individual compounds. More advanced statistical and toxicological approaches can help identify exposure patterns that deserve further study.

Priority 6: Investigate possible biological mechanisms

Research can examine whether particular exposures influence pathways involved in neurodevelopment, hormone signaling, inflammation, or cellular energy metabolism. Such work must connect laboratory findings with realistic human exposures and well-designed population studies.

Priority 7: Separate autism risk research from individual diagnosis

Even if future studies identify an environmental exposure that contributes to autism risk at a population level, that would not mean the exposure explains every autistic person's development.

Research should improve prevention of established hazards, deepen understanding of developmental biology, and support autistic people and their families—not create a search for blame.

9. The Reading Sage Perspective: Protect Children's Health Without Pathologizing Difference

The most useful response to emerging environmental-health research is neither dismissal nor alarmism.

We should not dismiss evidence that children encounter numerous environmental chemicals or that some exposures can harm development. Public health has a legitimate role in identifying hazards, evaluating exposure, and reducing preventable harm.

But we must also resist the temptation to turn a small observational study into a simple explanation for a complex neurodevelopmental condition.

Autistic children are not a uniform group. They have different strengths, support needs, communication styles, sensory experiences, and developmental trajectories. Their educational needs cannot be understood through a chemical exposure profile.

For teachers, the immediate responsibility remains to create learning environments that are safe, responsive, and accessible. That means observing the individual child, adapting instruction, providing communication supports, and helping children participate meaningfully in school and community life.

Environmental research can complement that work. It should never replace individualized educational planning or respectful understanding of neurodiversity.

A thoughtful public conversation can hold two ideas at once: reducing harmful environmental exposures is a worthwhile public-health goal, and autistic children deserve support and acceptance regardless of what future research discovers about the causes of autism.

Conclusion: A Promising Research Tool, Not a Final Answer

The 2026 University of Texas at San Antonio study offers an intriguing contribution to environmental-health research. In a small sample of shed baby teeth, researchers observed higher concentrations of 57 out of 60 frequently detected compounds in the autism group, with 19 differences reaching statistical significance.

The use of primary teeth provides a potentially valuable way to investigate chemical exposures across early developmental periods. The findings also highlight gaps in knowledge about the chemicals found in everyday environments and the need for more comprehensive exposure assessment.

However, the study does not demonstrate that the identified compounds caused autism, that baby bottles were responsible for individual children's exposures, or that reducing exposure to these compounds would prevent autism.

Those are questions for future research.

For parents and educators, the sensible response is to support evidence-based environmental health protections, seek reliable information about specific hazards, and avoid unnecessary fear or blame.

For researchers, the task is to replicate the findings, improve exposure measurements, account for alternative explanations, and investigate the biological significance of the observed differences.

For schools, the responsibility remains clear: protect children's health, respect developmental differences, and provide every child with the opportunity to learn and thrive.

Reading Sage takeaway: Follow the evidence, reduce established environmental hazards, and follow the child. Good science should expand our understanding—not narrow our compassion.

 This is an important topic for Reading Sage, especially because it sits at the intersection of developmental neuroscience, environmental health, early childhood development, and the need to distinguish scientific evidence from popular claims. The strongest version of this article will examine the baby-teeth study alongside the broader literature, explain what the findings do and do not establish, and give parents and educators practical guidance without creating unnecessary fear or implying that autism is caused by a particular product or parenting choice.

One important distinction up front: finding higher chemical concentrations in the teeth of children with autism does not establish that those chemicals caused autism. Researchers must still determine when exposure occurred, whether it preceded the development of autism-related traits, how the chemicals affect the developing brain, and whether the findings can be replicated in larger populations.
