Fetal Alcohol Spectrum Disorder
Worried About FASD in Your 12-to-18-Month-Old?
FASD is caused by alcohol exposure in pregnancy, not by anything in toddlerhood, and a full diagnosis usually cannot be confirmed at 12–18 months. 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.
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.
In short
Fetal 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.What is reasonable to watch at this age
If 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:- Growth — poor weight gain or smaller head size flagged at routine checks
- Feeding and sleep — ongoing difficulty settling, irritability or feeding struggles
- Movement — not yet pulling to stand, cruising or taking first steps by ~15–18 months
- Communication — few or no babbled words, limited pointing or gestures, little response to name
- Connection — reduced eye contact or shared attention compared with other toddlers
None 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.
When assessment becomes meaningful
A 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.The Pinnacle way
A clinical AbilityScore® 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 developmental story and, where there is a known prenatal history, supports you without judgement. Early, gentle developmental and behavioural support helps families build the predictable, nurturing routines every child thrives on, and you can read more about Fetal Alcohol Spectrum Disorder at your own pace.Trusted sources

Book a developmental check with a Pinnacle clinician.
What to watch
Watch broad development rather than FASD-specific signs at this age: poor weight gain or small head size flagged at checks, ongoing feeding or sleep struggles, not pulling to stand or cruising by ~15–18 months, few babbled words or gestures, and reduced eye contact. Share any prenatal alcohol history with a clinician — it is the most helpful thing you can do.
Try this at home
Build steady, predictable daily routines — the same wind-down before sleep, narrating what you do together, and plenty of face-to-face talk and play. Consistency and warm responsiveness support every toddler's growing brain, and they cost nothing.

Frequently asked
Can FASD be diagnosed at 12 to 18 months?
Usually not with confidence. FASD is caused by alcohol exposure in pregnancy, but its effects on learning, attention and behaviour only become clear as a child grows. At this age, clinicians monitor growth and general milestones rather than confirming a label.
What should I do if I drank alcohol during pregnancy?
Share that history honestly with your clinician — without shame. It is the single most helpful thing you can do, because it lets the team monitor your child's development closely and begin early support if needed. It does not change how warmly your child will be cared for.
What signs are worth watching at this age?
Watch general development: poor weight gain or small head size at checks, ongoing feeding or sleep difficulty, not pulling to stand or cruising by around 15–18 months, few babbled words or gestures, and reduced eye contact. These are signals for a gentle check, not a diagnosis.
