Worrying about FASD in your 6-to-9-month-old

If you drank alcohol during pregnancy — perhaps before you knew — and now find yourself watching your baby closely, that worry comes from love, and it deserves a calm, honest answer.

In short

At 6 to 9 months, there is usually no single sign that confirms or rules out Fetal Alcohol Spectrum Disorder (FASD, ICD-11 LD2F.00). FASD is caused by alcohol exposure before birth — not by anything you can do now — and its fuller picture (learning, attention, behaviour) typically emerges only in the toddler and school years. What is appropriate at this age is gentle developmental monitoring and, if there was known prenatal alcohol exposure, a proactive conversation with a clinician so your baby is followed kindly over time.

What is reasonable to observe at this age

Rather than hunting for a label, watch your baby's everyday development the way you would for any infant:

• Feeding and growth — steady weight gain, settled feeding
• Calming and sleep — some babies with prenatal exposure are more irritable or harder to soothe; share this honestly with your doctor
• Social connection — smiling, eye contact, turning to your voice, babbling back by around 6–9 months
• Movement — reaching, rolling, beginning to sit, bringing hands and objects to the middle

None of these, on their own, points to FASD. A history of alcohol in pregnancy is the most important piece of information — and the most helpful thing you can do is tell your paediatrician openly, without shame. That honesty lets your child be watched and supported early, which is exactly what helps most.

When assessment becomes meaningful

A confident FASD evaluation usually comes later, when growth, facial features, and developmental patterns can be reviewed together, often around the preschool years. For now, the path is monitoring, not diagnosis. Seek a developmental check sooner if you notice persistent feeding difficulty, poor weight gain, very marked irritability, stiffness or floppiness, or your baby is not smiling, babbling or responding to you by 9 months.

The Pinnacle way

A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online form or a checklist. With 4.95 lakh+ families supported across 70+ centres, our team can follow your baby gently over the months ahead, and our early intervention and developmental support focuses on strengths and steady progress rather than labels. If you'd value reassurance now, a calm developmental review is the kindest first step.

Next step — If you drank during pregnancy or simply want peace of mind, book a developmental check with a Pinnacle clinician who will follow your baby with care.
