Fetal Alcohol Spectrum Disorder (FASD) and Selective Mutism can both leave a young child quiet, but they are very different. FASD is a lifelong neurodevelopmental condition caused by alcohol exposure before birth, affecting learning, growth, attention, behaviour and sometimes facial features — and its difficulties appear across every setting. Selective Mutism is an anxiety-based condition where a child speaks freely in safe places like home but cannot speak in others like school; their language is intact. The key clue is consistency: FASD challenges are everywhere, while Selective Mutism silence is selective.

*Both can leave a young child quiet and hard to reach — but one begins before birth, and the other lives in anxiety.*

## In short
**Fetal Alcohol Spectrum Disorder (FASD)** and **Selective Mutism** can look alike at a glance — a child who is quiet, struggles to keep up, or seems different from peers — but they come from completely different places. FASD is a lifelong neurodevelopmental condition caused by alcohol exposure in the womb, affecting learning, growth, behaviour and sometimes facial features. Selective Mutism is an anxiety-based condition where a child *can* speak comfortably in safe settings (usually home) but consistently *cannot* speak in others (often school) — their language is intact; their voice is locked by fear. In short: FASD is about how the brain developed before birth; Selective Mutism is about anxiety in the present.

## How they differ in everyday life
A child with **FASD** may show challenges across many areas at once — slower learning, difficulty with memory and attention, trouble managing emotions or understanding consequences, smaller growth, and sometimes distinctive facial features. The difficulties are broad and present in *every* setting, not just one, because they reflect how the developing brain was affected. Language may be delayed across the board, at home and outside.

A child with **Selective Mutism** typically talks, laughs and chatters freely at home with close family — but goes silent at preschool, with relatives, or in shops. This is not stubbornness or rudeness, and it is not a language delay; the words are there. It is intense social anxiety that physically freezes speech in specific situations. Outside those triggers, their development is usually on track.

The key clue: **consistency**. FASD difficulties appear everywhere; Selective Mutism silence is *selective* — present in some places, absent in others. That single pattern often points a clinician in the right direction.

## When to seek a look
If your child is quiet in some settings but speaks freely at home, gently note where and with whom — that map is gold for a clinician assessing anxiety. If there are broader delays across learning, growth, attention and behaviour in every setting — especially with known prenatal alcohol exposure — a wider developmental assessment is the right path. Either way, early support helps enormously, and neither condition is a verdict on what your child can achieve.

## The Pinnacle way
This is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our team observes how your child communicates and copes across different settings, then shapes support — drawing on [speech therapy](/speech-therapy) and [behavioural therapy](/behavioural-therapy) as needed.
