Seek a developmental check if your baby consistently does not respond to sounds or their name, is unusually distressed or unbothered by touch and movement, or is not reaching for and exploring objects. Any hearing or vision concern deserves a prompt check. This is a reason to assess early — not a diagnosis.","answer_md":"*Babies explore the world through touch, sound, sight and movement — noticing how your little one responds is exactly the kind of loving attention that helps them flourish.*\n\n## In short\nBetween 9 and 12 months, most babies are busily reaching, mouthing toys, turning to sounds and enjoying cuddles — and there is a wide, healthy range of how strongly each baby reacts to the world. Gentle reasons to seek a developmental check include a baby who consistently does not respond to sounds or their name, seems unusually distressed or unbothered by touch, textures or movement, or who is not yet reaching for and exploring objects. This is not a diagnosis — it simply means a clinician's calm look is wise now, because early support works beautifully at this age.\n\n## What to watch at 9–12 months\nSensory development at this age is about how your baby takes in and responds to sound, sight, touch and movement. Most variation is completely typical. Gentle flags worth a clinician's eye include:\n\n- **Sound and hearing** — not turning towards your voice or everyday sounds, not startling to loud noises, or not responding to their own name. Any concern about hearing deserves a prompt check, as early hearing support matters greatly.\n- **Looking and tracking** — not following moving objects or faces with their eyes, not making eye contact, or eyes that seem not to focus together.\n- **Touch and textures** — very strong, persistent distress with everyday touch, clothing, bathing or new food textures, or the opposite — seeming not to notice touch, bumps or temperature.\n- **Movement and body** — strong dislike of being moved, tilted or held in different positions, or seeming floppy or very stiff when handled.\n- **Exploring** — not reaching for, grasping or mouthing toys, or little interest in exploring objects with hands and mouth.\n\nThe aim is not alarm — a calm, early observation turns small questions into early opportunities.\n\n## When to act\nIf you have any concern about your baby's hearing or vision, arrange a check promptly — these senses underpin so much learning. If your baby consistently shows several of the signs above, or your instinct simply says something is different, a developmental review now is wise rather than waiting. What you notice every day is genuinely valuable.\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.
