Focus on enjoying shared smiles, eye contact, babble and response to your voice, and raise any concern at your routine developmental and hearing checks. Formal autism assessment becomes meaningful from around 18–24 months.","answer_md":"*At six to nine months, a baby is just beginning to learn the dance of connection — and what you notice now is the start of a gentle conversation, not a diagnosis.*\n\n## In short\nAt 6–9 months, autism cannot be reliably identified — babies this young are still developing the social and communication skills we would later look at. What you *can* do is watch how your baby connects and shares joy with you, and raise anything that feels different at your routine developmental check. A formal autism assessment only becomes meaningful later, usually from around 18–24 months onward.\n\n## What is appropriate to notice at this age\nRather than \"signs of autism\", these are simply the warm, social building blocks most babies are growing into around now:\n\n- **Shared smiles** — does your baby smile back when you smile, and enjoy gentle back-and-forth play like peek-a-boo?\n- **Eye contact and faces** — does your baby look at your face and hold your gaze during feeds and cuddles?\n- **Sounds and babble** — by around 9 months, many babies babble (\"ba-ba\", \"da-da\") and turn toward sounds.\n- **Responding to you** — settling to your voice, turning when spoken to, reaching to be picked up.\n- **Hearing** — startling to loud sounds and quietening to familiar voices.\n\nBabies vary enormously, and one quiet week means very little. These are things to *enjoy and observe* — not a checklist to worry over.\n\n## When assessment becomes meaningful\nAutism ([ICD-11 6A02](/autism)) is recognised through patterns in social communication and behaviour that become clearer as a child grows — typically observable from around 18 months and assessed reliably from about 2 years. The most important thing at 6–9 months is a **general developmental check** with your paediatrician, and a **hearing check** if babble or response to sound seems limited, since hearing affects early communication.\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. If you ever have concerns, a structured developmental check can map your baby's strengths early, and [early intervention](/autism-therapy) support is there if and when it is needed.\n\n## Trusted sources\nAligned with WHO ICD-11 (6A02), CDC \"Learn the Signs.
