Every child has sensory preferences — one child loves rough-and-tumble play while another hates being touched, one is drawn to loud music while another covers their ears at background noise. But for some children, the difference goes beyond preference. Everyday sensory experiences — the hum of a shopping centre, the label in a shirt, the smell of a crowded room — can tip them into genuine distress.
If your child regularly seems overwhelmed by things that don't bother other children, this guide is for you.
What is sensory processing?
Sensory processing is the way the nervous system receives, organises, and responds to information from the senses. Most people think of the five main senses, but the nervous system also processes information about body position and movement (proprioception) and the vestibular sense (balance and spatial orientation).
For most people, sensory processing happens automatically in the background. The brain filters out irrelevant information (the hum of the fridge, the weight of clothes on the skin) and highlights important signals. This filtering happens without conscious effort.
For some children, this filtering process works differently. They may:
- Over-respond: Experiencing sensory input as more intense than it actually is. The seam in a sock feels like sandpaper. A moderately loud noise is physically painful. Light touch feels alarming.
- Under-respond: Needing more input than usual to register sensation. These children may seek intense sensory experiences — crashing into things, touching everything, loving very spicy or strong-flavoured foods.
- Have difficulty processing specific senses: One child might be fine with noise but extremely sensitive to textures. Another might struggle with movement and balance.
These patterns can exist on their own or alongside other conditions like autism, ADHD, or anxiety. They can also occur without any other diagnosis.
What sensory overwhelm looks like in children
Sensory overwhelm doesn't always look like what parents expect. A child who is overwhelmed may:
- Have a meltdown that seems out of proportion to what happened (from an outside perspective)
- Refuse to wear certain clothes, eat certain textures, or be in certain environments
- Become aggressive, clingy, or shut down when overstimulated
- Struggle to settle after transitions — arriving at school, finishing an activity, leaving a party
- Cover their ears, hide under furniture, or seek a quiet corner
- Avoid social situations that are loud or unpredictable
- Seek intense pressure or movement: bear hugs, crashing into cushions, constant spinning
Conversely, a child who under-responds may seem unaware of pain or temperature, be clumsy or accident-prone, constantly touch other people or objects, or crave intensely strong sensory experiences.
Both patterns — over- and under-response — can significantly affect a child's ability to participate in everyday activities like getting dressed, eating meals, attending childcare, and learning at school.
How occupational therapy can help
Occupational therapy (OT) is the primary profession that assesses and supports sensory processing differences in children. An occupational therapist with paediatric experience can:
- Assess your child's sensory processing profile across different senses and environments
- Work out which everyday activities are being affected and why
- Develop a sensory diet — a personalised programme of activities that help regulate your child's nervous system throughout the day
- Advise on environmental modifications (lighting, seating, clothing, transitions)
- Work with schools and childcare centres to put supports in place
Sensory-based OT intervention can make a significant difference to daily life — for the child and for the whole family. Many parents describe it as finally having a map to their child's inner experience.
Practical strategies for everyday life
While you're working with a professional or waiting for an assessment, some general strategies can help:
- Prepare for transitions: Give warnings ("in five minutes we're leaving the park") and keep transition routines consistent
- Create a calm-down space: A quiet corner with low light, soft textures, and a weighted blanket or cushion can help an overwhelmed child regulate
- Limit the warning signs: If you know a particular environment is hard, plan shorter visits and build in breaks
- Follow the child's lead on clothing: Label-free clothing, seamless socks, and soft fabrics make a real practical difference for touch-sensitive children
- Heavy work activities: Pushing, pulling, carrying, and climbing provide proprioceptive input that many sensory-seeking children find regulating
These strategies help, but they work best when tailored to your individual child by a professional who has assessed their specific sensory profile.
Frequently asked questions
Is sensory processing disorder a real diagnosis?
"Sensory processing disorder" is not currently a standalone diagnosis in the DSM-5 (the main diagnostic manual used in Australia), but sensory differences are recognised as a feature of autism and are increasingly documented in ADHD and anxiety. Many occupational therapists and paediatricians take sensory difficulties seriously and provide support regardless of whether a formal diagnosis exists.
My child's childcare centre says it's just a behaviour problem. How do I respond?
Sensory overwhelm often looks like challenging behaviour from the outside — refusal, meltdowns, aggression — because it is. The child is overwhelmed and reacting. Understanding the sensory cause changes the approach. An OT can provide a written report and recommendations to share with the childcare centre.
How do I access an OT for my child?
Your GP can provide a referral, which may unlock Medicare rebates under a Chronic Disease Management plan. If your child has an NDIS plan, occupational therapy is typically a funded support. Many families access OT privately, with or without a referral.
Next steps
If your child's sensory responses are affecting their daily life — at home, at childcare, or at school — it's worth talking to your GP about a referral to an occupational therapist. You don't need to have all the answers about what's going on before you make that call.
