Understanding Sensory Seeking in ADHD

 

"Why is my child always chewing on their sleeves?"

"Why can't they stop chewing pencils, hoodie strings or even their fingernails?"

These are questions I hear regularly from parents and teachers. While it can be frustrating (and expensive replacing school stationery!), chewing is often not a behaviour that a child simply chooses. For many children with ADHD, it is their brain's way of seeking the sensory input it needs to feel calm, focused and regulated.

 

Understanding why this happens is the first step towards responding with empathy rather than frustration.

 

What is Sensory Seeking?

Our brains constantly process information from our senses - what we see, hear, touch, smell, taste and how our bodies move through space.

Some children with ADHD process this sensory information differently. Their nervous systems may crave additional sensory input to help them stay alert, focused or emotionally regulated. This is known as sensory seeking.

 

Sensory seeking isn't "bad behaviour" or a sign that a child is being naughty. It is often their body's way of saying:

"I need help concentrating."

"I'm feeling overwhelmed."

"I need to regulate my emotions."

"My body needs more sensory input."

Many children with ADHD experience sensory differences, although not every child will have the same sensory needs.

 

Why Do Children with ADHD Chew?

Chewing is one of the most common forms of sensory seeking.

The muscles in our jaw provide powerful sensory feedback to the brain. For some children, chewing helps to:

• Improve concentration during class or homework.

• Reduce feelings of stress or anxiety.

• Stay alert during tasks that require sustained attention.

• Self-soothe during overwhelming situations.

• Release nervous energy.

This is why you may notice your child chewing clothing, pencils, erasers, hoodie strings, water bottle lids or even their own fingernails.

They're usually not trying to be difficult - they're trying to regulate their nervous system.

 

It's About Regulation, Not Discipline

Imagine trying to sit through a long meeting while feeling restless, uncomfortable and unable to focus.

Now imagine someone telling you to "just sit still."

 

For many children with ADHD, sensory seeking feels very similar. Asking them to simply stop chewing without offering another way to meet that sensory need can be incredibly difficult.

Rather than asking, "How do I stop this behaviour?" it can be more helpful to ask:

"What is my child trying to tell me?"

Often, the behaviour is communicating a need.

 

How Parents and Teachers Can Help

Instead of removing the behaviour altogether, try providing appropriate alternatives that meet the same sensory need.

Helpful strategies include:

• Regular movement breaks throughout the day.

• Access to fidget tools.

• Heavy work activities such as carrying books or pushing chairs.

• Opportunities to stand or stretch.

• A safe chewable sensory aid instead of clothing or pencils.

• A weighted lap pad during seated activities to provide calming deep-pressure input.

These supports aren't rewards - they're tools that help children regulate their attention and emotions so they can participate more successfully in learning and daily activities.

 

Supporting, Not Changing

Every child with ADHD is different.

Some children seek movement.

Others seek touch.

Some crave deep pressure.

Others seek oral sensory input through chewing.

When we understand these behaviours through a sensory lens, our response changes from correction to support.

A child who feels understood is far more likely to feel confident, accepted and capable.

 

Final Thoughts

Sensory seeking isn't something to be "fixed." It's something to be understood.

By recognising the reasons behind behaviours like chewing or constant fidgeting, parents and teachers can replace frustration with curiosity and create environments where children feel safe, supported and ready to learn.

 

Sometimes, a simple sensory tool - such as a chewable sensory necklace or a weighted lap pad - can make a meaningful difference by giving a child an appropriate way to meet their sensory needs while staying engaged in the classroom, at home or on the go.

 

At Cog-nature Kids, I believe that when we understand the why behind a child's behaviour, we can respond with compassion, practical strategies and the right support to help them thrive.
