Sensory Processing Differences: Signs Families Notice and How OT Helps
Maybe it's the daily battle over socks. Or the child who spins until they're dizzy, covers their ears in the supermarket, or gags at anything green. If you're searching for answers at 11pm, take a breath you're not alone, and there are practical, respectful ways forward.
What "sensory processing" actually means
Every one of us takes in the world through our senses — not just the big five (sight, sound, smell, taste, touch), but also:
proprioception — our sense of body position and how much force we're using,
vestibular sense — our sense of movement and balance,
interoception — our sense of what's happening inside our bodies (hunger, a full bladder, a rising feeling of overwhelm).
Some brains turn the volume up on certain input, and down on others. That's a sensory processing difference — a different way of experiencing the world, not a behaviour problem or a parenting failure. You'll also see the term "sensory processing disorder" (SPD) used online; sensory differences are commonly part of how autistic people and people with ADHD experience the world, and an OT assessment can help you understand your child's specific profile.
Signs families often notice
Every child is different, but these patterns come up again and again:
In toddlers and pre-schoolers
Extreme reactions to haircuts, nail clipping, teeth brushing or nappy changes
Refusing certain clothes — seams, tags, shoes — or wanting to be barefoot always
Very limited food range, often based on texture, smell or colour
Constant movement: spinning, crashing, jumping, climbing furniture
Meltdowns in busy, noisy or unpredictable places (shops, parties, playgrounds)
Not seeming to notice mess on hands or face, or pain that "should" cause a reaction
In primary-school kids
Trouble sitting still or focusing in class; fidgeting, slumping, or needing to move
Overwhelm at assemblies, canteens, excursions or the school gate
Avoiding handwriting, PE, art or music (messy or loud activities)
"Explosions" after school — holding it together all day, then releasing at home
Difficulty knowing when they're hungry, tired, or need the toilet (interoception)
In teens and young adults
Avoiding crowds, bright lights or noisy spaces like cafés and public transport
Relying on same foods, same clothes, same routines to feel steady
Exhaustion after masking sensory discomfort all day
Seeking intense input — heavy exercise, deep pressure, loud music — to regulate
Seeking, avoiding or both?
Sensory seekers crank the volume up: they crave movement, deep pressure, strong flavours, loud sounds.
Sensory avoiders turn it down: they retreat from touch, noise, smells and busy places.
Many people are mixed seeking in some senses, avoiding in others, even within the same day.
None of these is "better". The question isn't how do we stop this? It's what does this person's nervous system need, and how do we build a life that works with it?
When is it worth an occupational therapy assessment?
Consider reaching out if sensory differences are:
getting in the way — of mealtimes, sleep, school attendance, friendships or family outings,
causing distress — frequent meltdowns, anxiety about particular places or tasks,
affecting participation — your child is missing out on things they'd actually enjoy,
or you simply feel stuck and want a plan.
You don't need a referral or a diagnosis to start that conversation.
What occupational therapy actually does about it
A neurodiversity-affirming OT doesn't try to make your child "normal". They work with your child and family to:
Understand the profile — through observation, play-based assessment and your expertise as the parent.
Adapt environments — lighting, noise, seating, routines: changing the demands, not just the child.
Build regulation toolkits — movement breaks, deep pressure, fidgets, quiet spaces, planned "recharge" time after school.
Grow skills through what the child loves — using interests as the engine for new skills.
Support the adults around the child — so strategies travel to home, kinder, school and community.
Gentle starting points you can try at home
Notice and name patterns. When do hard moments happen? Before transitions? In noisy places? Patterns are information.
Offer movement before focus. A jump, a crash into cushions, a walk — movement often settles the system for sitting tasks.
Build a "calm kit" with your child: headphones, a favourite fidget, a soft toy, a visual of their quiet corner.
Protect recovery time. After a big day, lower the demands before expecting flexibility.
Follow their leads. Interests are the most motivating therapy material there is.
These ideas help many families — but they're starting points, not a substitute for individualised support.
Frequently asked questions
Is sensory processing disorder a real diagnosis? "Sensory processing disorder" isn't a standalone diagnosis in the DSM-5, but sensory differences are widely recognised and are a core area of occupational therapy practice. An OT assessment focuses on function: what's hard, what helps, and what support makes sense.
Will my child grow out of it? Profiles change with maturity and support. The most reliable path is building understanding and strategies now, rather than waiting.
Do we need a referral to see an OT? At Planet Ability, no referral is needed — families can enquire directly, and we support neurodivergent people aged 2 to 35, including via telehealth Australia-wide.
Can a school or kindergarten do anything in the meantime? Yes — teachers can often make simple adjustments (seating, movement breaks, quiet exit options). Our team also supports schools directly, and we've written a guide on talking to your child's school about neurodiversity.
The takeaway
Sensory differences are information, not defiance. When you understand what your child's nervous system is asking for, thing can get easier routines, outings, school, and family life.
