Watch gently for babbling, responding to name, early gestures and warm eye contact over weeks, not a single day. Persistent patterns or any loss of skills deserve a friendly developmental check, not alarm.","answer_md":"*At nine to twelve months your baby is just beginning to share their world with you — and noticing how they connect matters far more than any checklist.*\n\n## In short\nAt 9–12 months, autism is not yet diagnosed — this is a window to *gently observe* how your baby shares attention, sounds and smiles with you, not to look for a label. A few early social-communication patterns are worth watching, but one quiet day or a shy baby is not a worry. If a pattern persists across weeks and settings, a simple developmental check is the right, reassuring next step.\n\n## What to watch (gently, not anxiously)\nThese are *things to notice over time*, not a diagnosis:\n\n- **Sharing joy** — does your baby look at you, smile back, and enjoy turn-taking games like peek-a-boo?\n- **Responding to name** — by around 9–12 months, many babies turn or look when you call them.\n- **Babbling** — strings of sounds like \"ba-ba\", \"da-da\" usually emerge in this window.\n- **Early gestures** — beginning to wave, reach to be picked up, or look where you point.\n- **Eye contact** — comfortable, warm glances during cuddles and play.\n\nA single missing item is common and usually settles. It's the *pattern over weeks*, especially with little babble or gesture by 12 months, or any loss of skills already gained, that deserves a friendly check.\n\n## The science, simply\nAutism ([ICD-11 6A02](/autism)) describes differences in social communication and behaviour that become clearly recognisable later in the second year and beyond. In infancy, development naturally varies hugely. That's why global guidance favours *watchful, supportive monitoring* now — celebrating connection and acting promptly only if concerns persist.\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 — never from an online list.
