A reliable autism assessment usually becomes meaningful from around 18–24 months, when social-communication patterns are clearer. What you can do right now is observe a few specific things, keep enjoying everyday connection, and book a general developmental check so any support starts early — early support helps every baby, whatever the eventual picture.\n\n## What is worth watching at 9–12 months\nThis is the age of *connection*, not diagnosis. Rather than hunting for \"signs of autism\", gently notice how your baby responds and reaches out:\n\n- **Eye contact and shared smiles** — does your baby look at your face and smile back during play?\n- **Responding to their name** — by around 9–12 months, do they turn or look when you call?\n- **Pointing and showing** — do they reach, point, or hold things up to share with you?\n- **Babbling and gestures** — back-and-forth sounds, waving, copying simple actions like clapping.\n- **Joint attention** — following your gaze or pointed finger to look at the same thing.\n\nIf one or two of these are not yet emerging, that alone is **not** a diagnosis — babies develop on wonderfully varied timelines. It is simply a reason to mention it at a developmental check, so you have a clear baseline.\n\n## When assessment becomes meaningful\nFormal autism evaluation typically becomes reliable from **18–24 months**, because the social-communication patterns clinicians look for take time to show clearly. Before then, the most useful step is a **general developmental check** that looks at the whole picture — communication, play, motor skills and hearing. (A hearing check matters here, as undetected hearing differences can look like social-communication delay.) If you ever see loss of skills your baby once had, mention it promptly.\n\n## The Pinnacle way\nA clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a web page, a checklist or your baby's age alone.
