Sensory processing, explained

Your child will beg to be spun until they’re dizzy, then come apart when the hand dryer goes off in a public bathroom. That isn’t a contradiction, and it isn’t inconsistency. It’s one nervous system running eight separate volume dials.

Parent-to-parent guidance, not medical advice. Sensory differences are usually sorted out by an occupational therapist (OT), and they’re also part of what an autism evaluation looks at. This page exists so the vocabulary makes sense before you’re sitting in that appointment.

Why the same child seeks one thing and can’t stand another

Every sensory system has its own threshold — how much input it takes before the brain registers “that happened.” Where the threshold is high, ordinary input barely lands, so your child goes looking for more: spinning, crashing, chewing, humming, touching everything in the aisle. That’s seeking. Where it’s low, input arrives instantly and at full blast — a tag feels like a scratch, a gym sounds like a runway — and your child gets away from it however they can. That’s avoiding.

Here’s the part nobody explains: those dials are set independently. A child can be a devoted movement seeker and a sound avoider and barely notice a scraped knee, all before breakfast. Most people are a mix. Your child’s mix is just further from the middle.

The dials also move. Picture a bucket filling all day — the store that went fine Saturday morning is a disaster at 5:00 Friday, because the bucket started full. Illness, hunger, and poor sleep all lower the line.

None of this is behavior in the discipline sense. A kid with hands over their ears in Kroger isn’t being difficult. They’re being accurate.

The eight senses, in plain language

Five you learned in kindergarten, and three you probably didn’t — and those last three usually do the most work.

Sight — what the eyes take in

Seeking: ceiling fans, spinning wheels, objects lined up at eye level, light-up toys, the same clip watched frame by frame.

Avoiding: squinting under store fluorescents, hating the overhead light at bedtime, a classroom with posters on every wall, hiding from the salon mirror.

Meet the need: sunglasses or a ball cap in stores, lamps instead of overheads at night, a visually quiet corner at home, and a spinner that’s theirs to stare at guilt-free.

Sound — what the ears take in

Seeking: TV cranked up, humming and vocal play, banging cabinet doors, needing noise to fall asleep.

Avoiding: hands over ears at the hand dryer, panic at clipper noise during a haircut, refusing the school cafeteria, the store PA announcement that ends the trip.

Meet the need: headphones or loop earplugs in every bag, a warning before anything loud, music or a fan at bedtime, and somewhere at home they’re allowed to be loud.

Touch — what the skin reports

Seeking: touching every surface in the store, messy play, the tightest clothes, rubbing a favorite fabric, constantly climbing into your lap.

Avoiding: tags, seams, sock lines; refusing food that makes hands sticky; the cape and the loose hair down the neck at a haircut; jumping when hugged from behind.

Meet the need: tagless shirts, seamless socks, labels cut out. Firm pressure lands far better than light touch — press, don’t tickle. Keep a wet cloth at the table, and let them approach touch on their own terms.

Taste — flavor and food in the mouth

Seeking: sour candy, spicy food, lemon wedges, extremely crunchy things, licking or mouthing non-food items.

Avoiding: a diet that keeps shrinking, gagging on anything mixed together, one brand only, dinner as a nightly standoff.

Meet the need: a safe food on the plate at every meal, no pressure and no bite-counting, strong flavors and crunchy textures offered alongside. Refusal is sensory information, not defiance — call a feeding therapist or OT if the list keeps shrinking.

Smell — what the nose reports

Seeking: sniffing food, markers, laundry, people; a favorite blanket that must smell right.

Avoiding: gagging on cafeteria smell before the tray is even down, the salon’s shampoo, cleaning products, someone’s perfume in a checkout line.

Meet the need: go unscented at home, ask the school about a lunch spot outside the cafeteria, and try a preferred smell on a wrist or shirt collar to travel with them into hard rooms.

Vestibular — movement and balance (the inner ear)

Seeking: spinning without dizziness, swinging forever, hanging upside off the couch, jumping, never sitting still through a meal or a lesson.

Avoiding: carsickness, fear of feet leaving the ground, hating escalators and climbers, real distress when the head tips back at the salon sink or the bathtub.

Meet the need: movement before hard things — a swing before school, a lap around the store before the cart fills. Support the feet: a stool under a dangling foot at dinner steadies the whole body. For avoiders, keep the head upright, move slowly, warn first.

Proprioception — body awareness and deep pressure

Seeking: crashing into couch cushions, bear hugs, chewing shirt collars and pencils, heavy blankets, leaning on people, stomping.

Under-registering looks similar from outside: bumping into doorframes, breaking toys by accident, hugging too hard, writing that tears the paper.

Meet the need: heavy work — carrying groceries in, pushing the laundry basket, wall pushes, monkey bars, animal walks. It’s the most reliably calming input there is, and it’s the same short list before a haircut, before the store, and after school. A chewy necklace is a tool, not a habit to break.

Interoception — signals from inside the body

Hunger, thirst, the bathroom, pain, temperature, and the early physical feel of anger or anxiety.

Under-registering: no hunger cue until it’s a meltdown, accidents long past potty training, not noticing an injury, shorts in January, fine to furious with nothing in between.

Over-registering: ordinary hunger feels alarming, every stomach flutter is a crisis, a full bladder is unbearable at bedtime.

Meet the need: stop waiting for signals that don’t arrive — put snacks, drinks, and bathroom trips on the clock. Name sensations out loud as they happen: “your tummy is growling, that’s hungry,” “your hands are in fists, that’s mad coming.” Noticing is a teachable skill.

The same five places, every week

  • Mealtimes. Feet supported, overhead light off, a safe food always present, a wet cloth within reach, heavy work before you call everyone to the table.
  • Bedtime. Lamps not ceiling lights, sound handled on purpose (white noise or silence — pick per kid), a long routine of squeezes or a tight tuck, and a bathroom trip scheduled rather than requested.
  • School. Movement breaks before the wheels come off, headphones for the cafeteria, seating away from the vent and the door, a pass to leave a loud room — asked for in writing. Our IEP & 504 guide covers how.
  • Haircuts. Heavy work first, headphones on, cape skipped if the fabric is the problem, shirt changed right after so no hair sits on the neck. Book the quiet hour, or try a salon that plans for this — see sensory-friendly haircuts.
  • Stores. Go early, keep the list short, sunglasses and headphones in the bag, let them push the cart for the pressure, and leave before the bucket overflows. A short successful trip beats a long one that ends in the parking lot.

Meet the need instead of stopping the behavior

When you see spinning, chewing, crashing, or covered ears, the useful question isn’t “how do I stop this?” — it’s “what is their body asking for?” Stop the behavior and the need stays put. It always finds another door.

  • Give the input before the hard thing, not after the meltdown.
  • Change the environment before you try to change the child.
  • Never take away a regulation tool as a consequence. Headphones and chewies aren’t privileges.
  • Stop when they say stop. Pushing a child through avoidance to “get them used to it” usually makes it worse.
  • Write down what actually works. That list is worth more than any product.

The everyday version of all of this lives in our parenting tips.

When to bring in an OT

If sensory needs are running your family’s calendar — meals, sleep, getting dressed, leaving the house — that’s what a pediatric occupational therapist does all day. An OT maps your child’s profile system by system, builds a “sensory menu” that fits your actual house, and coaches you instead of only working with your child in a gym.

Families here often start with SOAR and the other OTs in the directory. Ask any practice: “How do you approach sensory work, and how much of it is parent coaching?” You want an answer about your whole week, not just the therapy hour.
