Between 9 and 12 months most babies respond to their name, play social games like peek-a-boo, share attention by following a point, use gestures such as waving, and show feelings by cuddling familiar people or being wary of strangers. These are gentle ranges, not strict deadlines.

*Somewhere between nine and twelve months, your baby starts to discover that other people are the most interesting thing in the room — and that's a milestone all its own.*

## In short
Between 9 and 12 months, most babies become wonderfully sociable: they wave or play games like peek-a-boo, look when you call their name, share their joy by smiling at you, and may show shyness around strangers. These are typical [social](/social) milestones (ICF d7 · interpersonal interactions) — gentle ranges, not a checklist with hard deadlines.

## What you may see by 12 months
- **Responds to their name** by turning or looking toward you
- **Plays social games** — peek-a-boo, pat-a-cake, give-and-take with toys
- **Shares attention** — looks where you point, then back at you ("joint attention")
- **Uses early gestures** — waving bye-bye, reaching up to be lifted, pointing or showing things
- **Shows feelings socially** — cuddles familiar people, may be wary of strangers, copies simple actions like clapping

## The science, simply
Social development at this age is about back-and-forth connection — the baby learns that a smile invites a smile, a point invites a look. These tiny exchanges are the foundation of later language and friendship. Babies develop at their own pace, so one slower skill alongside many strong ones is rarely a worry. What matters more is the overall pattern of warm, two-way engagement.

## The Pinnacle way
A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — this article is for guidance, not diagnosis. If you'd like reassurance, our [behaviour therapy](/behaviour-therapy) and developmental teams can map your baby's [social](/social) strengths and gently flag anything worth watching.

## Trusted sources
Aligned with the WHO ICF framework for interpersonal interactions (d7), and developmental guidance from the CDC and the American Academy of Pediatrics.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
