Early Signs of Fetal Alcohol Spectrum Disorder at 6–9 Months

When you know there may have been alcohol exposure in pregnancy, every milestone can feel weighted with worry — but watching gently and getting the right support early changes everything.

In short

Fetal Alcohol Spectrum Disorder (FASD) is linked to alcohol exposure before birth, so in a 6-to-9-month-old the early signs are subtle and watched-for rather than diagnosed. They can include slower growth, mild feeding and sleep difficulties, lower muscle tone, being unusually irritable or hard to settle, and gentle delays in sitting or reaching. Many of these signs are non-specific and common in healthy babies — only a qualified clinician can weigh them together, especially where prenatal alcohol exposure is known.

Early signs to watch for at 6–9 months

Growth and body

• Slower weight gain or growth that tracks below expectation
• Lower muscle tone (a baby who feels a little 'floppy') or, less often, stiffness
• Subtle facial features are sometimes noted by clinicians — these are assessed medically, not from a photo at home

Feeding and sleep

• Difficulty with feeding — weak or uncoordinated suck-swallow, slow feeds
• Disrupted, light or irregular sleep

Behaviour and development

• Being unusually irritable, jittery or hard to soothe
• Heightened sensitivity to light, sound or handling
• Gentle delays in motor milestones — sitting steadily, reaching, transferring toys

These signs overlap with ordinary variation in healthy babies and with other causes entirely. What matters most is the pattern over time and whether there was known alcohol exposure in pregnancy.

When to seek a check

If you know or suspect alcohol exposure during pregnancy, share this openly and early with your paediatrician — without blame, simply so your baby gets the right monitoring. Seek a developmental check when growth falters, when feeding or settling is a persistent struggle, or when motor milestones lag across several weeks. Honest disclosure protects your child; FASD support works best when started early.
