At this age, watch general development — growth, feeding, movement and early communication — and share any known prenatal alcohol history honestly. Confident assessment comes later, in the preschool and school years; for now a general developmental check is the right step. Only a Pinnacle clinician can assess, never an online form.","answer_md":"*If you know — or wonder — whether alcohol reached your baby in pregnancy, and you're now watching your 12-to-18-month-old for signs, that worry comes from a place of deep love.*\n\n## In short\nFetal Alcohol Spectrum Disorder (FASD) begins before birth — it is caused by alcohol exposure during pregnancy, not by anything in toddlerhood. At 12–18 months a full FASD picture cannot usually be confirmed, because the learning, attention and behaviour difficulties it can bring only become clear as your child grows. What you *can* do now is watch general development — growth, feeding, sleep, movement and early communication — and share any known prenatal alcohol history honestly with a clinician. These are things to monitor, not a diagnosis.\n\n## What is reasonable to watch at this age\nIf there was alcohol exposure in pregnancy, the most useful thing is to track whether your toddler is meeting broad milestones, and to mention the history without shame so the right support can begin early:\n\n- **Growth** — poor weight gain or smaller head size flagged at routine checks\n- **Feeding and sleep** — ongoing difficulty settling, irritability or feeding struggles\n- **Movement** — not yet pulling to stand, cruising or taking first steps by ~15–18 months\n- **Communication** — few or no babbled words, limited pointing or gestures, little response to name\n- **Connection** — reduced eye contact or shared attention compared with other toddlers\n\nNone of these alone means FASD — they are general developmental signals worth a gentle check. The honest reporting of any prenatal alcohol use is the single most helpful thing you can offer, and it changes nothing about how warmly your child will be supported.\n\n## When assessment becomes meaningful\nA confident FASD assessment usually comes later — often in the preschool and school years — when learning, attention, memory and behaviour can be properly observed. Right now, the right step is a **general developmental check**, not a label. If you have concerns at any point, an early conversation lets a clinician monitor growth and milestones over time and put support in place well before school.\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 form or a checklist.
