Fetal Alcohol Spectrum Disorder
Early Signs of FASD in a 12-to-18-Month-Old
By 12–18 months, early signs of FASD after prenatal alcohol exposure can include slow growth, a smaller head, feeding and sleep difficulties, an irritable hard-to-settle temperament, delays in sitting, crawling or walking, low muscle tone, and fewer babbles and gestures. These are gentle prompts to seek a developmental check — not a diagnosis to make at home, and never a parent's fault to carry alone.
If alcohol was part of a pregnancy and your little one feels a step behind, you're not alone — and there is much that gentle, early support can do.
In short
Fetal Alcohol Spectrum Disorder (FASD) follows prenatal alcohol exposure, so it isn't something that suddenly "appears" — but by 12–18 months you may notice signs such as slower growth, feeding and sleep difficulties, delays in sitting, crawling or walking, fewer babbles and first words, and an unusually irritable or hard-to-settle temperament. Some children also show subtle facial features or a smaller head. These are gentle prompts to seek a developmental check — not a diagnosis you can make at home, and importantly, not your fault to carry alone.Early signs to watch (12–18 months)
Growth and physical cues- Slow weight gain or being small for age (poor growth before and after birth)
- A smaller-than-expected head circumference noted at health checks
- Subtle facial features sometimes linked with FASD — a thin upper lip, smooth area between nose and lip, smaller eye openings (these need a clinician's eye, not a home check)
Feeding, sleep and regulation
- Difficulty feeding, poor suck earlier on, or fussiness around food
- Disrupted, restless sleep and trouble settling
- An easily overwhelmed, irritable temperament — hard to soothe, very sensitive to noise, light or touch
Movement and milestones
- Delays in sitting steadily, crawling or pulling to stand and walking
- Low muscle tone (floppiness) or, conversely, stiffness; clumsy or jerky movements
- Delays in fine motor skills like picking up small objects with finger and thumb
Communication and connection
- Fewer babbles, gestures (waving, pointing) or first words than expected by 18 months
- Less back-and-forth social engagement
Many of these overlap with ordinary variation in development. What matters is the pattern — several signs together, alongside a known history of prenatal alcohol exposure.
When to seek a check
If alcohol was used during pregnancy, that history alone is reason enough to ask for a developmental review — early support helps most when it begins early. Seek a check sooner if your child is not sitting or babbling by around 12 months, not walking or using gestures and words by 18 months, growing very slowly, or is persistently difficult to feed and settle. A thoughtful assessment looks at the whole child — growth, movement, communication and regulation together.The Pinnacle way
At Pinnacle Blooms Network, we begin with warmth and the whole picture — never blame. Early support such as occupational therapy for movement, feeding and sensory regulation, alongside communication-building, can make a real difference in these foundation years. A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care; nothing here is a diagnosis. Across 70+ centres in 4 states and 4.95 lakh+ families served, our aim is steady, strengths-first progress for your child.Trusted sources

What to watch
Watch for slow growth or a small head, feeding and sleep difficulties, an easily overwhelmed irritable temperament, low muscle tone, delays in sitting, crawling or walking by 18 months, and fewer babbles, gestures or first words — especially with a history of prenatal alcohol exposure.
Try this at home
Build calm, predictable routines around feeds and sleep, and offer plenty of slow, gentle face-to-face talk and naming of everyday objects — steady, low-stimulation interaction helps an easily overwhelmed little one engage and learn.

Frequently asked
Can FASD be seen at 12 to 18 months?
FASD stems from prenatal alcohol exposure, so it doesn't suddenly appear — but by 12–18 months you may notice signs such as slow growth, a smaller head, feeding and sleep difficulties, an irritable temperament, delays in sitting, crawling or walking, and fewer babbles or words. A clinician can review these alongside the pregnancy history; a full diagnosis is made only by qualified professionals.
If I drank during pregnancy, does that mean my child will have FASD?
Not necessarily — outcomes vary widely. But a history of prenatal alcohol exposure is good reason to ask for a developmental review, because early support helps most when it begins early. This is about giving your child the best start, not about blame.
What should I do if I notice these signs?
Book a developmental check rather than trying to diagnose at home. A thoughtful assessment looks at growth, movement, feeding, regulation and communication together, and from there a gentle, strengths-first support plan can begin.
