By 12–18 months, most toddlers share smiles, follow your gaze, point to show things, respond to their name, and copy gestures like waving. Seek a developmental check if your toddler rarely makes eye contact, doesn't point or show objects, doesn't respond to their name, shows little interest in shared play, or has lost a social skill. These are reasons to assess early, not a diagnosis — early support works best at this age.

*Between one and one-and-a-half, your toddler is learning that people are the most interesting thing in the world — noticing how they connect is loving, watchful parenting.*

## In short
By 12–18 months, most toddlers share smiles, follow your gaze, point to show you things, respond to their name, and copy little actions like waving or clapping. Gentle reasons to seek a developmental check are when your toddler **rarely makes eye contact, doesn't point or show you objects, seems not to notice when you come or go, doesn't respond to their name, or shows little interest in playing alongside you**. None of this is a diagnosis — it simply means a clinician's calm look is wise now, because early support at this age works beautifully.

## What to watch at 12–18 months
Social connection blooms fast in this window. Most toddlers are turning into little communicators — even before words arrive. Gentle flags worth a clinician's eye include:

- **Limited eye contact** — rarely looking to your face to share a moment, a smile, or to check your reaction.
- **Not pointing or showing** — not pointing at things they want or find interesting, and not bringing toys over to show you (this "shared attention" is a key social milestone).
- **Not responding to their name** — consistently not turning when you call, when hearing is not the issue.
- **Little back-and-forth** — not waving bye-bye, clapping, copying simple gestures, or joining in playful give-and-take like peekaboo.
- **Seeming content alone** — not seeking you out for comfort or play, or not noticing when you leave or return.
- **Loss of a skill** — any social warmth, babble, or gesture that was there and has faded deserves prompt review.

The aim is never alarm — it's that a calm, early observation turns small questions into early opportunities.

## When to act
If several of these are present, or if your gut tells you something has changed, arrange a developmental check now rather than waiting and watching. Trust the parent instinct — what you see every day at home is valuable clinical information.
