Early Signs of FASD in a 1-Year-Old Boy

When a baby is just turning one, every parent wonders if they are growing the way they should — and if you carried a worry about alcohol in pregnancy, that question can feel especially heavy. Let's look at this gently and clearly.

In short

Fetal Alcohol Spectrum Disorder (FASD) is linked to alcohol exposure before birth, and some signs can be present from infancy. At one year, the picture is usually subtle — feeding and sleep difficulties, slower growth, fussiness, and gentle delays in movement or interaction — rather than anything dramatic. None of these alone confirms FASD; only a qualified clinician can assess and explain what they mean for your son.

Early signs sometimes seen around 12 months

Growth and feeding

• Slower weight gain or being small for his age, despite feeding
• Difficulty with feeding — weak suck, easily tired, fussy or messy feeding
• Disrupted, irregular sleep that's hard to settle

Behaviour and temperament

• Marked irritability, being easily overwhelmed by noise, light or touch
• Difficulty being soothed and calming back down

Movement and interaction

• Slower progress with sitting, crawling or pulling to stand
• Less back-and-forth smiling, babble or shared attention than expected
• Sometimes subtle facial features, noted only by a trained clinician

Many healthy babies show one or two of these for entirely ordinary reasons. What matters is a pattern that persists — and a known history of alcohol exposure makes a developmental check worthwhile.

What's most appropriate at this age

A firm FASD picture often becomes clearer as a child grows and learning, attention and behaviour can be observed. At one year, the kindest and most useful step is a thorough general developmental check — tracking growth, feeding, movement and early communication — rather than waiting. If you know alcohol was used in pregnancy, please share that openly with your clinician; it helps them help your son, and there is no judgement in it.
