Babies develop at very different rates — one may be walking while another is still crawling, and both can be perfectly typical.

Children do some of these, not all at once — variation is normal.","q":"What should a 12-month-old be able to do?"},{"a":"Consider a developmental check if your baby isn't babbling or making sounds, doesn't respond to their name, shows no eye contact or shared smiles, isn't sitting on their own, or has lost skills they once had. Acting on a gentle worry early is always worthwhile.","q":"When should I get my baby checked?"},{"a":"No. A difference at this age is not a diagnosis. Many children catch up on their own, and others benefit from early support.

Trust your instinct: a gentle clinician-led developmental check either reassures you or helps you act early. Any AbilityScore or diagnosis is formed only at a Pinnacle centre.","answer_md":"*Noticing your little one isn't doing quite what other babies are — that worry comes from love, and it's worth listening to.*\n\n## In short\nAt 12 months, babies vary hugely — some are cruising along furniture while others are still happily bottom-shuffling, and both can be perfectly fine. So no, a single difference is usually not a cause for alarm. But your instinct as a parent matters, and a gentle developmental check is the calm, sensible next step — it either reassures you or helps you act early, and both are good outcomes.\n\n## What's typical (and worth watching) around 12 months\nMost children around their first birthday are doing *some* of these — not every single one, and not all at once:\n\n- **Communication** — babbling with ups and downs, responding to their name, maybe a first word or two\n- **Social** — looking at you, sharing smiles, pointing or reaching to show you things, playing peek-a-boo\n- **Movement** — sitting steadily, pulling to stand, picking up small bits with finger and thumb\n- **Understanding** — turning to familiar sounds, following a simple gesture like \"come here\"\n\nGentle flags worth a check: not babbling or making sounds at all, no response to their name, no eye contact or shared smiles, not sitting on their own, or losing skills they once had. A flag is a *reason to look*, never a verdict.\n\n## The Pinnacle way\nAt this age the goal isn't a label — it's a clear picture. A clinical **AbilityScore®** and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online checklist.
