Early Signs of Fetal Alcohol Spectrum Disorder at 18–24 Months

If alcohol may have reached your baby in pregnancy, the gentle question now is how your toddler is growing, playing and connecting — not blame.

In short

In an 18-to-24-month-old, Fetal Alcohol Spectrum Disorder (FASD) tends to show as a cluster rather than a single sign: slower growth, delays in walking, talking and play, difficulty settling and sleeping, feeding troubles, and sometimes subtle facial features. None of these on their own means FASD — many have everyday causes — but where there was known or possible alcohol exposure in pregnancy, this is the right age for a careful developmental look. These are signs to observe and discuss, not to diagnose at home.

Early signs to watch at 18–24 months

Growth and physical

• Low weight, height or head size, or slow growth despite good feeding
• Subtle facial features sometimes linked with prenatal alcohol exposure (a smooth area between nose and lip, a thin upper lip, smaller eye openings)
• Feeding difficulties, fussiness or poor weight gain

Movement and play

• Delays in walking steadily, climbing or using hands for small tasks
• Clumsiness or low muscle tone (a "floppy" feel)

Communication and learning

• Few or no words by around 18–24 months, or limited pointing and gesturing
• Difficulty following simple instructions or imitating play

Behaviour and regulation

• Marked trouble settling, irregular or disrupted sleep
• Easily overwhelmed, very irritable, or hard to soothe
• Big reactions to everyday sounds, textures or routine changes

What raises attention is a known or possible history of alcohol in pregnancy alongside several of these together, rather than one delay in isolation.

When to seek a check

Because FASD reflects how the developing brain was affected before birth, early support genuinely changes the path. Arrange a developmental check if there was any alcohol exposure in pregnancy and you notice growth, movement, speech or sleep concerns — or simply if your gut says your toddler isn't tracking as expected. Honest information about pregnancy helps clinicians, and is met without judgement; it is the single most useful thing you can share.

The Pinnacle way

At Pinnacle Blooms Network, we start with your child's strengths and what daily life feels like — then build a plan around play, communication and regulation. Support such as speech therapy and early developmental therapy helps language, movement and self-soothing grow step by step. 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.

Trusted sources

Aligned with WHO ICD-11 (LD2F.00, Fetal alcohol syndrome within the spectrum of prenatal alcohol effects), the American Academy of Pediatrics and HealthyChildren.org guidance on early development and developmental surveillance, and CDC information on FASD and developmental milestones.
