A clinician considers it where there is a known or possible history of prenatal alcohol exposure alongside differences in growth, milestones or regulation. Sharing that history honestly is protective, not blameworthy. Only a Pinnacle clinician can assess; never an online form.","answer_md":"*If you're wondering whether your toddler's development might be touched by Fetal Alcohol Spectrum Disorder, that worry deserves a calm, clear answer — not a frightening checklist.*\n\n## In short\nFetal Alcohol Spectrum Disorder (FASD) is caused by alcohol exposure during pregnancy — so it is not something a child \"develops\" later, and not something your toddler's behaviour at 18–24 months could *cause*. At this age, FASD is not diagnosed from a list of toddler behaviours; rather, a clinician considers it where there is a known or possible history of prenatal alcohol exposure alongside differences in growth, development, or how a child learns and regulates. These are signs to gently observe and discuss with a clinician — never to self-diagnose. If alcohol exposure in pregnancy is a real possibility, that history alone is reason enough for a developmental check.\n\n## What is appropriate to observe at 18–24 months\nAt this age we watch broad developmental progress rather than hunting for a specific label. Where there is concern about prenatal alcohol exposure, a clinician may note patterns such as:\n\n- **Growth differences** — being persistently small for age in height, weight or head size\n- **Delays in milestones** — later first words, fewer than expected by 24 months, or wobbly walking and fine-motor skills\n- **Feeding and sleep difficulties** that feel harder than usual to settle\n- **Big swings in regulation** — intense difficulty calming, unusual sensitivity to noise, touch or routine changes\n- **Social and play differences** — limited eye contact, pointing or shared play\n\nNone of these alone means FASD — they overlap with many ordinary variations and other conditions. The single most important factor a clinician needs is an honest, non-judgemental history of any alcohol during pregnancy. Sharing that openly is one of the kindest, most protective things a parent can do.\n\n## When to seek a check\nArrange a developmental check if your child is behind on milestones, growing slowly, or having marked difficulty with regulation — and sooner if there is any history of alcohol exposure in pregnancy. FASD (ICD-11 LD2F.00) sits within developmental conditions, and early support helps a child thrive regardless of the eventual label. There is no blame here — only the chance to give your child the right help early.\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. Our team looks at your child's whole picture — growth, milestones, regulation and your family's story — with warmth and without judgement, drawing on 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres. Where support is needed, gentle [developmental therapy](/occupational-therapy) and a clear understanding of [Fetal Alcohol Spectrum Disorder](/fetal-alcohol-spectrum-disorder) help your child build skills step by step.\n\n## Trusted sources\nWHO ICD-11 (LD2F.00, Fetal Alcohol Spectrum Disorder); CDC guidance on FASD and prenatal alcohol exposure (cdc.gov); American Academy of Pediatrics developmental-surveillance guidance (healthychildren.org).\n\n**Next step —** If alcohol exposure in pregnancy is possible, or your toddler's development worries you, the kindest move is a calm clinician conversation. [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-18-to-24-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-18-to-24-month-old-might-have-fetal-alcohol-spectrum-disorder","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/when-should-i-worry-that-my-18-to-24-month-old-might-have-fetal-alcohol-spectrum-disorder-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"FASD Worries in 18–24-Month-Olds | Pinnacle","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"If alcohol during pregnancy is part of your story, write down what you can recall — timing and amounts — and share it openly with your clinician.
