Early Signs of FASD in a 3-to-6-Month-Old

When a parent worries about something that happened during pregnancy, the most loving thing to know is this — early understanding leads to early support, and support changes everything.

In short

Fetal Alcohol Spectrum Disorder (FASD) is linked to alcohol exposure before birth, so the watch begins from infancy rather than later. In a 3-to-6-month-old, possible early signs are usually subtle and physical — slower growth, feeding and sleep difficulties, irritability, low or unusual muscle tone, and sometimes distinctive facial features. None of these alone confirms FASD, and only a qualified clinician can assess properly. If there is any known prenatal alcohol exposure, an early developmental check is always worthwhile.

Early signs to watch for

Around growth and the body

• Lower-than-expected weight, length or head growth, or slow gains over time
• Subtle facial features sometimes described in FASD (a smoother area between nose and lip, thin upper lip, smaller eye openings)
• Low or unusually high muscle tone, or floppiness when held

Around feeding and sleep

• Difficulty latching, sucking or coordinating feeding
• Very disrupted, light or irregular sleep beyond the usual newborn pattern
• Frequent distress or hard-to-settle crying

Around state and responsiveness

• Marked irritability or being easily overwhelmed by sounds, light or handling
• Less settled, less rhythmic responses to soothing than expected for her age

Many of these signs overlap with ordinary infant fussiness, reflux or a passing phase — they matter most when several appear together, persist, or follow a known history of prenatal alcohol exposure.

When to seek a check

Because FASD relates to exposure before birth, there is no need to "wait and see" if you already know alcohol was used in pregnancy — share that openly with your paediatrician, as honest history guides kinder, earlier care. Seek a developmental check when growth is faltering, when feeding or sleep is persistently difficult, or whenever your own worry lingers. Early support for growth, feeding and regulation makes a real difference to how your baby thrives.
