If your baby is sitting with support, reaching, babbling and connecting with you, this is usually fine. If by around 9 months they cannot sit with support or feel very stiff or floppy, a gentle developmental check is wise.","q":"My baby isn't sitting unsupported yet at 8 months — should I worry?"},{"a":"If your baby was born early, look at milestones by their corrected age — that is, their age counted from the due date rather than the birth date — until around two years. This gives a fairer picture of where their development really is.","q":"Should I use my baby's actual age or corrected age?"},{"a":"Trust your instinct. Arrange a developmental review if, by around 9 months, your baby isn't sitting with support, makes few or no babbling sounds, doesn't turn to your voice or share smiles, doesn't reach for objects, or has lost a skill once had.

Your baby is likely on track if they respond to you and keep adding new skills. Seek a gentle developmental check if, by around 9 months, they aren't sitting with support, babbling, turning to your voice, sharing smiles or reaching for objects — or if they've lost a skill. These are reasons to look early, not a diagnosis.","answer_md":"*Watching your baby grow between 6 and 9 months is a season of big firsts — sitting, babbling, reaching for the world — and noticing what they do is loving, watchful parenting.*\n\n## In short\nMost 6-to-9-month-olds are busy sitting, babbling, rolling, reaching and beginning to explore — and there's a wide, normal range of when each skill appears. Your baby is likely on track if they are responding to you, showing interest in faces and objects, and steadily adding new skills month by month. This isn't a test to pass — if anything gives you pause, a gentle developmental check is a wise, calm next step, because early support works beautifully at this age.\n\n## What's typical at 6–9 months\nBabies bloom at their own pace, but by this window many will be:\n\n- **Moving** — sitting with less and less support, rolling both ways, pushing up on hands, and perhaps starting to scoot or rock on all fours.\n- **Reaching and grasping** — passing toys hand to hand, raking small things towards them, bringing objects to the mouth to explore.\n- **Communicating** — babbling with strings of sounds (\"bababa\", \"mamama\"), turning to your voice, laughing and squealing.\n- **Connecting** — smiling at familiar faces, enjoying peek-a-boo, showing they know you from a stranger.\n\nRemember: a baby born early should be looked at by their **corrected age**, and a skill arriving a few weeks later than a chart says is usually still well within normal.\n\n## When a gentle check is wise\nTrust your instinct and arrange a developmental review if, by around 9 months, your baby:\n\n- Is not sitting with support, or feels very stiff or very floppy in your arms.\n- Makes few or no babbling sounds, or has gone quiet after starting.\n- Does not turn to your voice, share smiles, or show interest in faces and games.\n- Does not reach for or hold objects, or strongly favours one hand only.\n- Has **lost** a skill they once had — this always deserves prompt review.\n\nNone of these is a diagnosis. They simply mean a clinician's calm, early look turns small questions into early opportunities.\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 checklist.
