Is it behaviour or sensory overload?

A child covers their ears at a birthday party. They refuse to wear certain clothes. They become upset in a busy shopping centre or seem unable to sit still at the dinner table.

It can be easy to interpret these responses as difficult behaviour. Sometimes, however, the child’s nervous system is working very hard to process what is happening around them.

Understanding sensory processing can help us look beyond the behaviour and ask a more helpful question: what might this child be experiencing right now?

What is sensory processing?

We are constantly receiving information through our senses. This includes the familiar senses of sight, sound, touch, taste and smell, as well as senses that tell us about movement, balance and where our body is in space.

The brain needs to notice, organise and respond to all this information. This is known as sensory processing.

Every person processes sensory information differently. One child may love noisy, active environments, while another finds the same environment exhausting or overwhelming. Some children actively seek movement and touch, while others avoid particular sensations.

These differences are not automatically a concern. Support may be helpful when sensory responses begin to affect a child’s comfort, participation, learning or family life.

What can sensory overload look like?

Sensory overload can look different for every child. Possible signs include:

• Covering their ears or becoming distressed around everyday sounds

• Avoiding crowded, noisy or brightly lit environments

• Refusing certain clothes because of seams, tags or fabric textures

• Becoming upset during hair brushing, toothbrushing or nail cutting

• Avoiding messy play or particular food textures

• Constantly seeking movement, jumping, crashing or spinning

• Finding it difficult to remain seated or still

• Becoming unusually quiet, withdrawn or unresponsive

• Having a strong emotional reaction after school or a busy outing

• Struggling when several instructions are given at once

A child experiencing sensory overload is not necessarily choosing to be uncooperative. Their system may have reached the point where it cannot comfortably manage any more information.

How can occupational therapy help?

An occupational therapist can help identify the sensory experiences that may be affecting a child and understand how these relate to their everyday activities.

The goal is not to stop a child from being sensitive or to force them to tolerate distress. The goal is to support participation, build skills and make environments more manageable.

Strategies may include:

• Adjusting the environment

• Preparing the child before transitions or unfamiliar experiences

• Introducing movement or calming activities

• Breaking tasks into smaller steps

• Supporting the child to recognise their body’s signals

• Finding alternatives for difficult textures or sensations

• Working with parents and teachers to create consistent support

There is no single sensory strategy that works for every child. What settles one child may be alerting or uncomfortable for another, which is why individual assessment is important.

Looking beneath the behaviour

Behaviour is often communication. A child may not yet have the words to explain that a room is too loud, their clothing feels painful or their body needs movement before it can concentrate.

When we become curious about what sits beneath the behaviour, we can respond with greater compassion and provide more useful support.

If sensory differences are making everyday routines, learning or community activities difficult for your child, Stepping Stones OT can help you understand their needs and explore practical strategies.
