45 | Mouthing & Chewing Behaviors in Autism | Dipali Devani

Many autistic children chew on clothing, toys, or even their own hands. While this behavior can feel confusing or concerning for parents, it often serves an important purpose for the child.

In this episode of the Autism Family Resource Podcast, Brian Keene is joined by occupational therapist Dipali Devani for another conversation in the Common Chaos Sensory Series. Together they explore why mouthing and chewing behaviors happen and how parents can support their child’s sensory needs in healthy, safe ways.

Understanding the “why” behind these behaviors can help families respond with confidence instead of worry. When we look at these behaviors through a sensory lens, we often discover that children are simply trying to regulate their bodies.

Memorable Quote

“Children often chew or mouth objects because their body is trying to regulate itself—they’re simply trying to get the sensory input they need.”

Key Themes From the Conversation

Understanding Oral Sensory Needs

Many children explore the world through their mouths during early development. However, when chewing or mouthing continues beyond early childhood or becomes excessive, it may indicate a sensory need.

Some children seek strong input through their mouth because it helps them regulate their nervous system. Chewing, sucking, or biting can provide deep pressure that helps them feel calmer or more focused.

Recognizing When to Seek Support

Mouthing behaviors are very typical in babies and toddlers because they explore objects through their mouths. This phase usually decreases as children grow.

If a child continues chewing on non-food items past age three to five, or if the behavior interferes with daily activities, it may be helpful to seek support from an occupational therapist who specializes in sensory processing.

Why Regulation Matters

Children often repeat behaviors that help their bodies feel more regulated. If chewing helps reduce anxiety or increase focus, they may rely on it frequently.

Instead of trying to stop the behavior entirely, the goal is to help the child meet their sensory needs in safer and more functional ways.

Sensory Strategies That Can Help

Occupational therapists often introduce replacement strategies that provide similar sensory input.

These might include:

• Chewable sensory jewelry designed for safe chewing
• Deep pressure activities like animal walks
• Vibrating toothbrushes or oral sensory tools
• Blowing bubbles to activate oral muscles
• Drinking thick smoothies through a straw
• Sensory play or weight-bearing activities

Families can also create calming spaces at home where children can take sensory breaks when they feel overwhelmed.

Common Questions Parents Ask

Why does my child chew on their clothes or hands?

Many children chew or mouth objects to get sensory input that helps regulate their nervous system. It can also happen during moments of stress, boredom, or transitions.

Is chewing always a problem?

Not necessarily. Mouthing is common in early childhood. It becomes more important to investigate if the behavior continues past early developmental stages or interferes with eating, social participation, or safety.

What should I do if my child constantly chews things?

Start by observing patterns. Notice when the behavior happens most often and what might trigger it. An occupational therapist can help identify sensory needs and create strategies that support regulation.

Why This Conversation Matters for Families

When parents understand the sensory reasons behind behaviors like chewing or mouthing, it can shift the entire approach to support.

Instead of seeing the behavior as something to stop, families can begin asking a more helpful question: What sensory need is my child trying to meet?

With the right strategies, children can learn safer and more effective ways to regulate their bodies—supporting participation at home, school, and in social environments.
