These are gentle ranges, not strict deadlines.","answer_md":"*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.*\n\n## In short\nBetween 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.\n\n## What you may see by 12 months\n- **Responds to their name** by turning or looking toward you\n- **Plays social games** — peek-a-boo, pat-a-cake, give-and-take with toys\n- **Shares attention** — looks where you point, then back at you (\"joint attention\")\n- **Uses early gestures** — waving bye-bye, reaching up to be lifted, pointing or showing things\n- **Shows feelings socially** — cuddles familiar people, may be wary of strangers, copies simple actions like clapping\n\n## The science, simply\nSocial 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.\n\n## The Pinnacle way\nA 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.
