There is a wide normal range; a developmental check helps if your baby isn't exploring, recognising faces or responding to sounds by 9 months.","answer_md":"*Between six and nine months, your baby becomes a little explorer — curious, watchful, and learning that the world keeps existing even when it's out of sight.*\n\n## In short\nBy this age, most babies are exploring objects with growing intent — reaching, mouthing, banging and passing things hand to hand — and beginning to understand that things and people are still there when hidden. These are early thinking skills, and there's a wide, normal range. A few weeks either way is completely typical, especially for babies born early.\n\n## Cognitive milestones to look for (6–9 months)\n- **Exploring on purpose** — examines toys closely, turns them over, mouths and bangs them to learn how they work.\n- **Cause and effect** — repeats an action that makes something happen, like shaking a rattle or dropping a toy to watch it fall.\n- **Early object permanence** — looks for a partly hidden toy; by around 8–9 months may search for one fully covered.\n- **Attention and recognition** — knows familiar faces, may show wariness of strangers, and turns toward sounds and names.\n- **Hand-to-hand transfer** — passes an object from one hand to the other and brings two objects together.\n\nThese are signposts, not a checklist to pass. Babies grow in their own rhythm.\n\n## The science\nThe WHO ICF groups these under *mental functions (b1)* — attention, memory and early problem-solving that form the foundation for later [cognitive](/cognitive) learning. Curiosity-led play is how these connections are built.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online list. If you'd like reassurance or a baseline, explore our [special education](/special-education) support and learn [what the AbilityScore® is and how it's calculated](/ask/what-is-the-abilityscore-and-how-is-it-calculated).\n\n## Trusted sources\nGuided by the WHO International Classification of Functioning (mental functions, b1) and aligned with CDC \"Learn the Signs. Act Early.\" and AAP developmental guidance.\n\n**Next step —** if your baby isn't exploring objects, recognising familiar faces, or responding to sounds by 9 months, book a gentle developmental check on WhatsApp: +91 91001 81181.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-cognitive-milestones-should-my-6-to-9-month-old-have-reached","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
