If your child suddenly covers their ears when the vacuum cleaner starts, refuses a particular pair of socks, avoids certain foods, or seems to spend the day climbing, jumping, and crashing into things, you may start wondering what is behind it.
For many parents, these behaviours can be confusing. You might hear, “They're just being fussy,” or “They have so much energy.” Sometimes, though, there's another piece to the puzzle: the way a child experiences sensory information.
Understanding sensory processing can help parents look at these everyday situations from a different perspective.
What Is Sensory Processing?
Sensory processing is the way the brain receives information from the body and the surrounding environment and works out what to do with it.
Think about everything your child experiences during an ordinary day. There's the sound of traffic, the feeling of their clothes, the smell of lunch, bright lights, movement, touch, and changes in temperature. Their brain is constantly sorting through all of this information.
For most people, this happens without much conscious thought.
Is Sensory Processing Disorder a Diagnosis?
You may come across the term "sensory processing disorder" (SPD) when researching your child's behavior. However, SPD isn't currently recognized as a standalone diagnosis in Australia.
These difficulties can occur alongside autism or ADHD, but sensory differences aren't exclusive to children with those conditions. Each child's experience can be quite different.
We Have More Than Five Sensory Systems
Most of us learn about the five senses as children: sight, sound, smell, taste and touch.
There are also sensory systems that tell us about movement and what's happening inside our bodies.
-
Vestibular Sense
The vestibular system helps with balance, movement, and knowing how the body is positioned in relation to gravity.
-
Proprioception
Proprioception helps us understand where our body is without having to look at it. It also helps us judge how much force to use when pushing, pulling, jumping, or hugging.
-
Interoception
Interoception relates to signals from inside the body. Hunger, thirst, tiredness, temperature, and needing to use the toilet are all examples. Because these systems work together, sensory differences don't always look the same from one child to another.
Sensory Needs Can Change as Children Grow
A child's sensory preferences aren't necessarily set in stone.
A toddler may cry when something feels uncomfortable because they don't yet have the words to explain what's wrong. An older child might be able to tell you that a classroom is too noisy or that a particular jumper feels itchy. As children grow, their communication skills, routines, and environments change too. Their sensory needs can change along with them.
For parents wanting to understand these changes in more detail, our guide Sensory Sensitivities Change as Kids Grow looks at what parents may notice at different ages.
Common Sensory Responses in Children
There isn't a single way sensory differences appear. Some children avoid particular sensations, while others seem to search for them.
When Everyday Sensations Feel Too Strong
A child who is very sensitive to certain sensory input might:
-
Cover their ears around loud or unexpected sounds
-
Refuse clothing with tags or seams
-
Avoid foods because of their texture
-
Become upset during haircuts or teeth brushing
-
Find crowded places overwhelming
-
Dislike bright lights
-
Avoid messy or unfamiliar activities
From a parent's perspective, the reaction may seem surprisingly strong.
But telling a child that something “isn't that loud” doesn't necessarily change how it feels to them.
When a Child Looks for More Sensory Input
Other children seem to need more physical or sensory input throughout the day.
You may notice them:
-
Jumping or climbing whenever they get the chance
-
Running around constantly
-
Bumping into furniture
-
Enjoying rough-and-tumble games
-
Asking for tight hugs
-
Chewing on things
-
Seeking strong flavors or crunchy foods
-
Finding it difficult to stay seated
This behavior can sometimes be mistaken for simply having too much energy. In some cases, however, the child may be seeking the type of sensory input that helps them feel more comfortable and organized.
How Sensory Differences Affect Everyday Family Life
Sensory challenges don't only appear during obviously “sensory” activities. They can turn up during ordinary routines.
Getting Dressed
For some families, getting dressed can become the hardest part of the morning.
A particular sock seam, fabric, or waistband may bother a child enough that they refuse to put the clothing on. Trying different materials, removing labels, or finding clothing with fewer irritating seams may be worth exploring.
Mealtimes
Food isn't only about flavor.
Texture, smell, temperature, and appearance can all matter. A child might happily eat crunchy foods but refuse soft foods or become upset when different foods touch.
This doesn't always mean they're simply being a picky eater.
Bedtime
By the end of the day, a child has already dealt with hours of sounds, movement, social interaction, and other sensory information. Parents researching ways to create a more comfortable, sensory-friendly sleep environment may also come across sensory bedding in australia.
Sensory Processing at School
School brings its own collection of sensory experiences.
There may be conversations happening around the child, chairs scraping across floors, bells ringing, bright lights, crowded corridors, and unexpected changes to the day's routine.
For a child who is sensitive to noise or visual stimulation, this can become tiring. Another child may find sitting through a lesson difficult because they are constantly looking for movement.
When Sensory Needs Are Mistaken for Behavior
A child who repeatedly leaves their seat may be described as disruptive. A child who covers their ears might seem unwilling to participate. Someone who becomes distressed during transitions may simply appear to be having a tantrum.
Looking at what happened before the behavior can sometimes provide useful clues.
Practical Things Parents Can Try
You don't need to make huge changes overnight.
-
Create a Calm Spot
A quiet corner with familiar items can give your child somewhere to take a break when things become overwhelming.
-
Prepare Them for Transitions
A quick warning before leaving the park or starting bedtime can make an upcoming change less sudden.
-
Make Time for Movement
If your child loves to move, regular opportunities for running, jumping, or stretching can naturally become part of the day.
-
Keep Routines Familiar
Children often find routines easier when they know what comes next. A simple sequence such as bath → pyjamas → story → bed can provide that predictability.
When Should You Get Professional Support?
Not every sensory preference is a sign that something is wrong. Children can dislike certain foods, sounds, or fabrics without having significant sensory difficulties.
A pediatrician can help investigate your concerns. An occupational therapist can also assess how sensory experiences are affecting your child's participation in everyday activities and suggest strategies suited to their individual needs.
Final Thoughts
Sensory processing can sound complicated when you first encounter it, but understanding it often begins with paying closer attention to your child's everyday experiences.
-
Maybe that jumper really is uncomfortable.
-
Maybe the birthday party genuinely feels too loud.
-
Maybe all that jumping and crashing isn't simply “bad behavior."
-
Children experience the world in different ways, and those needs can change as they grow.
As a parent, you don't need to have every answer immediately. Start by noticing patterns, listening to what your child is communicating, and making small practical changes where appropriate.
Frequently Asked Questions
1. What are the common signs of sensory processing difficulties in children?
Signs can vary from child to child. Some children may cover their ears around loud sounds, dislike certain clothing textures, avoid particular foods, become overwhelmed in busy places, or seek constant movement and physical activity.
2. Is sensory processing disorder officially diagnosed in Australia?
Sensory Processing Disorder (SPD) is not currently recognized as a standalone diagnosis in Australia. Health professionals may instead describe a child as having sensory processing difficulties or sensory differences. A pediatrician or occupational therapist can help assess concerns based on the child's individual needs.
3. Can sensory processing difficulties change as a child gets older?
Yes. A child's sensory preferences and responses can change as they grow. Their communication skills, daily routines, school environment, and ability to manage different situations can all affect how sensory needs appear.
4. What can parents do to support a child with sensory needs?
Small changes can make everyday routines easier. Parents can create a quiet space, give advance warnings before transitions, allow regular movement breaks, choose comfortable clothing, and keep bedtime routines predictable. The most useful strategies depend on the individual child.
5. When should I seek professional help for sensory difficulties?
Consider speaking with a paediatrician or occupational therapist if sensory responses are frequent or intense and begin interfering with everyday activities such as eating, getting dressed, sleeping, attending school, or participating in family and social activities.
