It is never caused by the child, parenting or anything after birth. There is no known safe amount, and a clinical AbilityScore and diagnosis are formed only at a Pinnacle centre.","answer_md":"*The most reassuring fact about Fetal Alcohol Spectrum Disorder is also the simplest: it has one cause, and that cause is preventable.*\n\n## In short\nFetal Alcohol Spectrum Disorder (FASD) is caused by **alcohol crossing the placenta during pregnancy and reaching the developing baby**. Because a baby's body cannot break alcohol down the way an adult's can, it interferes with how the brain and other organs form. FASD is **not** caused by anything a young child did, by parenting, or by anything that happens after birth — the differences you see in a child today trace back to alcohol exposure before they were born.\n\n## How it happens\nAlcohol passes freely from a mother's bloodstream through the placenta to the baby. During pregnancy the brain is growing and wiring itself continuously, so exposure at almost any stage can affect how cells migrate and connect. This is why FASD can show up later as challenges with attention, learning, memory, movement, emotional regulation or growth — even when a child looks much like their peers.\n\nThere is no known safe amount, type or timing of alcohol in pregnancy, which is why the guidance is simply *no alcohol at any stage*. Importantly, a diagnosis is never about blame — many exposures happen before a pregnancy is even known. What matters now is understanding your child's unique profile so the right support can begin early, when the developing brain is most responsive.\n\n## The Pinnacle way\nA clinical AbilityScore® and any diagnosis are formed **only at a Pinnacle Blooms Network centre, by qualified clinicians** — never from an online tool. From there we map your child's strengths and needs and build a plan you can follow. Learn more about [Fetal Alcohol Spectrum Disorder](/fetal-alcohol-spectrum-disorder), explore how [occupational therapy](/occupational-therapy) supports everyday skills, and see [how the AbilityScore works](/ask/what-is-the-abilityscore-and-how-is-it-calculated).\n\n## Trusted sources\nWHO ICD-11 (LD2F.00); US CDC guidance on FASD and alcohol in pregnancy; American Academy of Pediatrics developmental guidance.\n\n**Next step —** Curious where your child stands today? [A Pinnacle clinician can map their profile](/fetal-alcohol-spectrum-disorder).\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-causes-fetal-alcohol-spectrum-disorder-in-young-children","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/what-causes-fetal-alcohol-spectrum-disorder-in-young-children","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/what-causes-fetal-alcohol-spectrum-disorder-in-young-children-te","lang":"te","indexable":true}],"meta_title":"What Causes Fetal Alcohol Spectrum Disorder?","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Keep simple, predictable routines and short, clear instructions — children affected by FASD often do far better when steps are broken down and the day is steady and familiar.","published_at":"2026-06-10T10:24:00.12799+00:00","what_to_watch":"In a young child with known prenatal alcohol exposure, watch for patterns over time rather than one moment: challenges with attention, memory, learning, emotional regulation, coordination, sleep, or slower growth.
