The most useful step now is to tell your paediatrician if there was any alcohol exposure in pregnancy, so your baby can be gently monitored. Observe growth, feeding and early milestones — and remember only a Pinnacle clinician can assess, never an online form.","answer_md":"*If you're looking closely at your 3-to-6-month-old and wondering whether something from pregnancy could be affecting them, that worry is understandable — and you deserve a calm, clear answer.*\n\n## In short\nFetal Alcohol Spectrum Disorder (FASD) is not a condition you can confirm at 3–6 months from a checklist, and most of its features — learning, attention, memory and behaviour difficulties — only become observable as your child grows. The key question at this age is simpler and more useful: **was there any alcohol exposure during pregnancy?** If yes, that alone is reason to tell your paediatrician early so your baby can be gently monitored over time — not because you should expect a crisis now. What's appropriate at this age is reassurance, observation of feeding, growth and early milestones, and a relationship with a clinician who knows your child's story.\n\n## What is — and isn't — meaningful at 3–6 months\nFASD ([ICD-11 LD2F.00](/fetal-alcohol-spectrum-disorder)) is caused by alcohol exposure before birth, and a careful diagnosis brings together exposure history, growth, certain facial features and developmental findings — assessed over time, not in a single infant snapshot.\n\nAt 3–6 months, rather than hunting for \"signs\", it's far more helpful to observe the everyday things every baby is checked for:\n\n- **Growth** — steady weight, length and head growth along their own curve\n- **Feeding** — feeds reasonably well, isn't excessively irritable or hard to settle at every feed\n- **Calming and sleep** — can be soothed; settles into emerging patterns\n- **Early milestones** — turning to sounds, beginning to smile socially, following faces, holding the head steadily, reaching towards objects by around 4–6 months\n\nThese are general developmental markers, not a test for FASD. A baby exposed to alcohol may show none of these difficulties — and difficulties here can have many ordinary, treatable causes.\n\n## When to speak to a clinician\nTell your paediatrician **if there was any alcohol exposure during pregnancy** — this is the single most important step, and it lets your baby be followed thoughtfully rather than diagnosed prematurely. Also seek a check sooner if your baby is not growing along their curve, is extremely difficult to feed or settle, is very stiff or very floppy, or is clearly behind on the early milestones above. None of these confirm FASD; they simply mean a kind, professional look is worthwhile now.\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.

[Book a developmental check](/enroll) with a Pinnacle clinician.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/when-should-i-worry-that-my-3-to-6-month-old-might-have-fetal-alcohol-spectrum-disorder","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU Consortium · Pinnacle Blooms Network"},"alternates":[{"href":"https://pinnacleblooms.org/ask/when-should-i-worry-that-my-3-to-6-month-old-might-have-fetal-alcohol-spectrum-disorder","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/when-should-i-worry-that-my-3-to-6-month-old-might-have-fetal-alcohol-spectrum-disorder-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"FASD Signs in a 3-6 Month Baby: When to Worry","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Keep a simple note of your baby's feeding, sleep and the moments they smile, turn to your voice or reach for things.
