# When do children usually develop sensory integration?

Sensory integration develops gradually from birth and grows fastest between 12 and 36 months, as toddlers learn to handle textures, sounds, movement and busy spaces. There's no single milestone date, and wide variation is normal. Persistently extreme reactions beyond the toddler years are worth a friendly developmental check.

*Your toddler tasting, touching, spinning and tumbling isn't chaos — it's the brain learning to make sense of the world, one sensation at a time.*

## In short
Sensory integration — the brain's way of taking in and organising what a child sees, hears, touches, tastes and feels through movement and balance — develops gradually from birth and grows fastest between **12 and 36 months**. There is no single date it 'arrives'; toddlers steadily get better at handling textures, sounds, movement and busy spaces across these years. Wide variation is normal.

## How it usually unfolds
- **Around 12–18 months** — explores textures by mouthing and touching, enjoys movement like being lifted or bounced, begins to settle more easily after a cuddle or familiar routine.
- **Around 18–24 months** — walks, climbs and tumbles to seek movement, tolerates a wider range of food textures and clothing, copes with everyday noise such as a mixer or doorbell.
- **Around 24–36 months** — manages messy play (sand, dough, paint), sits through short group activities, and recovers from upsets with a little help.

## The science
The vestibular (balance), proprioceptive (body-position) and touch systems mature with everyday play and repetition. ICF frames this under *b156 perceptual functions*. Reactions that stay very strong — extreme distress at sounds, textures or being moved, or constantly craving spinning and crashing — beyond the toddler years are worth a friendly developmental check rather than waiting.
