Developmental trauma and Fetal Alcohol Spectrum Disorder (FASD) can look alike in young children but have different roots. Developmental trauma comes from overwhelming early experiences — neglect, instability, loss — that shape how a child feels safe and regulates emotions. FASD is caused by alcohol exposure before birth, which affects how the brain itself formed, and may include specific growth and facial features in some children. Both can bring difficulties with regulation, attention and relationships, and a child can have both. Only a qualified clinician can tell them apart through a careful, whole-picture assessment.

*Two very different beginnings — one shaped before birth, one shaped by early experiences — that can look surprisingly alike in a young child.*

## In short
**Developmental trauma** describes the effects of overwhelming, repeated stress in a child's earliest relationships — neglect, frightening separations, instability or harm — that shape how a young child feels safe, trusts and regulates emotions. **Fetal Alcohol Spectrum Disorder (FASD)** is caused by alcohol exposure *before birth*, which affects how the brain itself formed. The key difference is the root: trauma comes from *experiences after conception*, while FASD comes from *prenatal alcohol affecting brain development*. They can look similar — both can bring big emotions, attention difficulties and trouble with routines — but they are understood and supported differently, and only a clinician can tell them apart.

## How they differ in everyday life
**Developmental trauma** is about a child's relational history. A young child who has lived through unpredictability or loss may be easily startled, struggle to settle, find it hard to trust adults, or swing between clingy and withdrawn. Their nervous system has learned that the world is unsafe, and their behaviour is often a survival response, not naughtiness. With safety, warmth and consistent care, many of these patterns can gently ease over time.

**FASD** has a biological footprint from pregnancy. Alongside emotional and attention difficulties, some children show specific features — differences in growth, certain facial characteristics in some children, and a particular profile of learning, memory and impulse-control challenges. These reflect how the brain was built, so support focuses on structure, predictability and adapting the environment to the child's wiring.

Because both can show difficulty with regulation, sleep, attention and relationships, they are easy to confuse — and a child can sometimes have *both*. That is exactly why a careful, whole-picture assessment matters far more than matching a behaviour to a label.

## When to seek a look
Seek a developmental check if a young child is persistently hard to settle, struggles with everyday routines, shows big or unexpected emotional swings, or if there is a known history of prenatal alcohol exposure or significant early adversity. Early understanding helps everyone respond with the right kind of support.

## 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 looks at your child's full story — history, development, strengths and needs — before suggesting anything. Learn more about [developmental trauma](/developmental-trauma) and how supportive [behavioural therapy](/behavioural-therapy) can help a child feel safe and regulated.
