FASD is caused by alcohol exposure during pregnancy, not by anything a toddler does — so at 18–24 months it is not diagnosed from a behaviour checklist. 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.

*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.*

## In short
Fetal 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.

## What is appropriate to observe at 18–24 months
At 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:

- **Growth differences** — being persistently small for age in height, weight or head size
- **Delays in milestones** — later first words, fewer than expected by 24 months, or wobbly walking and fine-motor skills
- **Feeding and sleep difficulties** that feel harder than usual to settle
- **Big swings in regulation** — intense difficulty calming, unusual sensitivity to noise, touch or routine changes
- **Social and play differences** — limited eye contact, pointing or shared play

None 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.

## When to seek a check
Arrange 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.

## The Pinnacle way
A 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.

## Trusted sources
WHO 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).

**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.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
