What it is
Some children respond to everyday sensory input — sounds, lights, textures, movement — in atypical ways. They may be over-responsive (easily overwhelmed by noise, tags, or bright light) or under-responsive (seeking intense movement or input). These sensory processing differences are real and can affect learning and comfort, though “sensory processing disorder” is not a standalone diagnosis in the main diagnostic manuals (the DSM-5 folds sensory hyper- and hypo-reactivity into the criteria for autism) and it often occurs alongside autism or ADHD.
Signs & characteristics
It can look different in every child. Common patterns:
- Over-responsiveCovers ears at noise, dislikes certain textures/clothing tags, avoids messy play, overwhelmed in busy rooms
- Under-responsiveSeeks movement, spins, crashes, chews, or seems not to notice input
- Big reactionsMeltdowns or shutdowns when overwhelmed
- Trouble focusingWhen the environment is too stimulating
- Motor/coordinationSometimes difficulty with balance or fine-motor tasks
Evaluation & testing
An occupational therapist (OT) is the professional who typically assesses sensory needs, often as part of a broader evaluation (since sensory differences frequently accompany autism or ADHD). At school, an evaluation can determine whether OT or accommodations are appropriate.
Supports & accommodations
Supports focus on the environment and coping tools:
- Adjust the environmentReduce noise/light; offer a quiet space or noise-reducing headphones
- Sensory toolsFidgets, weighted items, flexible seating, movement breaks
- PredictabilityWarn before transitions and loud events
- Occupational therapyBuilds strategies and, where helpful, a “sensory diet” of activities
- Respect the signalsMeltdowns are often overwhelm, not defiance — a calm, low-stimulation response helps
What families can do
What families can do: notice your child’s specific triggers and calming strategies, share them with the school, and ask about an OT evaluation if sensory needs affect learning or daily life. At home, build in predictable routines, offer calming spaces, and prepare your child for overwhelming situations in advance.
