At 18–24 months, most sensory behaviours — spinning, mouthing toys, loving or hating messy play, covering ears at loud sounds — are typical as your toddler learns how the world feels. Seek a developmental check if sensory responses are extreme and daily, disrupt eating, sleeping, dressing or play, or come with delays in talking, social connection or movement. These are reasons to assess early, not a diagnosis, because early support works best.

*Sniffing toys, spinning, covering ears, loving messy play or hating it — toddlers explore the world through their senses, and noticing how yours responds is wonderful, attentive parenting.*

## In short
At 18–24 months, most sensory behaviours are completely typical — your toddler is learning how sights, sounds, textures and movement feel, and reactions can swing from delighted to overwhelmed in minutes. A developmental check is wise when sensory responses are **extreme, persistent, get in the way of eating, sleeping, dressing or play**, or travel alongside delays in talking, social connection or movement. None of this is a diagnosis — it simply means a clinician's gentle look is worthwhile now, because early support works beautifully at this age.

## What's typical at 18–24 months
Toddlers at this stage are busy sensory explorers. The following are usually completely normal:

- **Seeking input** — spinning, jumping, crashing, climbing, squeezing into tight spaces, or loving deep hugs.
- **Mouthing and touching** — putting things in the mouth, smelling toys, running hands through sand, water or food.
- **Some sensitivities** — disliking loud noises, certain food textures, tags in clothes, or getting messy. Many toddlers cover their ears at a vacuum cleaner or fuss over a seam.
- **Big swings** — being thrilled one moment and overwhelmed the next, especially when tired, hungry or in a busy place.

These ebb and flow as your child's nervous system matures and language grows to help them tell you what they need.

## Gentle flags worth a clinician's eye
Consider a developmental check if you notice:

- **Extreme, daily distress** — meltdowns at everyday sounds, textures or lights that don't settle and disrupt routine.
- **Getting in the way** — sensory reactions that block eating a varied diet, sleeping, dressing, bathing or joining play.
- **Very limited play** — repeating one sensory action (spinning wheels, flicking lights) so much it crowds out other exploration.
- **Travelling with other differences** — few or no words, not responding to their name, little eye contact or shared smiling, not pointing, or loss of a skill once had.

The aim isn't alarm — it's turning small everyday questions into early opportunities.
