When to worry about FASD in a newborn

If you drank alcohol before you knew you were pregnant — or you're simply worried about your baby's earliest weeks — this is a caring, responsible question to ask.

In short

Fetal Alcohol Spectrum Disorder (ICD-11 LD2F.00) comes from alcohol exposure during pregnancy, not from anything that happens after birth. In the newborn weeks, FASD is usually not something you can confirm at home — most features become clearer as your baby grows and develops. The single most useful thing you can do now is share an honest history with your paediatrician, who can watch growth and development closely over time. Worrying alone helps no one; a calm conversation with a clinician does.

What is and isn't meaningful in the newborn period

FASD exists along a spectrum, and only some babies show recognisable signs at birth. A paediatrician — not a parent at home — looks for these in context:

• Growth — lower-than-expected birth weight or length, or slow weight gain
• Certain facial features — these are specific and subtle, and are assessed by a trained clinician, not from a phone photo
• Feeding, sleep and settling — some exposed babies are jittery, hard to console, or feed poorly in the early weeks

What you cannot reliably judge yet are the learning, attention, memory and behaviour aspects of FASD — these unfold across toddlerhood and the early school years. So the newborn stage is about honest history and watchful, supportive monitoring, never a home checklist or self-diagnosis.

When to speak to your doctor

Tell your paediatrician — without shame — if there was any alcohol exposure in pregnancy, even early or uncertain. Also seek a check if your newborn isn't gaining weight, is very difficult to feed or settle, or seems unusually stiff or jittery. Early, honest disclosure means your baby gets the right monitoring and support from the start — and if everything is developing well, that reassurance is precious too.
