Early Signs of FASD in a 12-to-18-Month-Old

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.
