By 6–9 months most babies are sharing smiles, turning to your voice, enjoying peek-a-boo and recognising familiar faces. Reasons to seek a gentle developmental check include rarely smiling back, not responding to your voice, little eye contact or shared joy, being hard to engage in back-and-forth play, or losing a social skill once had. This is not a diagnosis — babies vary widely — but an early calm look helps, because support works beautifully at this age.

*Those first belly-laughs, the peek-a-boo giggles, the way your baby lights up when you walk in — these are the social sparks we gently watch for at this age.*

## In short
By 6–9 months most babies are warming up socially — sharing smiles, turning to your voice, enjoying back-and-forth play like peek-a-boo, and showing they know familiar faces. A few gentle reasons to seek a developmental check are when your baby **rarely smiles back at you, doesn't turn or respond to your voice, shows little eye contact or shared joy, or seems hard to engage in playful to-and-fro**. None of this is a diagnosis — babies vary widely — but a calm clinician's look now is wise, because early support works beautifully at this age.

## What's typical — and what to watch — at 6–9 months
Social development at this stage is mostly about connection and back-and-forth. Lovely things you'll often see: a baby who smiles when you smile, babbles in a chatty back-and-forth, enjoys games like peek-a-boo, reaches to be picked up, watches faces closely, and shows they recognise familiar people. Many also begin to look wary of strangers — a healthy sign they know who's who.

Gentle flags that deserve a clinician's eye:

- **Little shared smiling** — rarely smiling back at you or responding to your warmth and silly faces.
- **Not responding to voice or name sounds** — not turning towards you, not seeming to notice familiar voices.
- **Limited eye contact or shared joy** — not following your gaze, not lighting up during cuddles or play.
- **Hard to engage** — little interest in back-and-forth games, or seeming content to be on their own most of the time.
- **Loss of a skill** — a social warmth or babble that was there and has faded.

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

## When to seek a check
If any of these are part of your everyday picture — especially several together, or a skill that has slipped — arrange a developmental check now rather than waiting. Trust your parent instinct; what you notice every day is valuable information for a clinician.
