FASD and GDD can look similar in young children but are different kinds of label. FASD is a cause-based diagnosis — difficulties arising from alcohol reaching a baby during pregnancy, affecting learning, attention, movement and sometimes growth and facial features, usually lifelong. GDD is a descriptive term meaning a child under five is significantly behind in two or more areas of development, without yet saying why; its causes are many, and alcohol exposure is just one. GDD asks 'what is hard now?', FASD can answer 'why?'. Both lead to the same first step: a developmental check and early support.

*Both can slow a young child's development — but one has a known cause from before birth, and the other is simply a description of what we see today.*

## In short
**Fetal Alcohol Spectrum Disorder (FASD)** and **Global Developmental Delay (GDD)** can look similar in a young child, but they are different kinds of label. FASD describes a group of difficulties caused by alcohol reaching a baby during pregnancy — it names a *cause*. GDD simply means a child under five is significantly behind in two or more areas of development (movement, talking, thinking, social skills) — it describes a *pattern*, without yet saying why. A child with FASD may carry a GDD description too; but GDD has many possible causes, and alcohol exposure is only one of them.

## How they differ in everyday life
**FASD** is a cause-based diagnosis. It can affect learning, attention, memory, movement, and sometimes facial features and growth — and the difficulties usually stay across the lifespan, though support changes outcomes greatly. A clinician looks for known alcohol exposure during pregnancy alongside the developmental picture.

**GDD** is a *temporary, descriptive* term used while a child is young and the full picture is still unfolding. It tells us a child needs support now, and it prompts a careful search for the reason — which might be genetic, related to prematurity, a medical condition, FASD, or sometimes never fully identified. As the child grows, GDD often becomes a clearer, more specific picture.

The key takeaway for parents: GDD answers *"what is my child finding hard right now?"* while FASD can answer *"why?"* in children with prenatal alcohol exposure. Both lead to the same kind first step — a proper developmental check and the right early support.

## When to seek a check
If your young child is noticeably behind in sitting, walking, babbling, talking, playing or connecting compared with other children their age, it is worth a developmental check — regardless of the eventual label. Early support helps every child make the most of their growing brain.

## 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 a form. Our team gently observes how your child moves, communicates, learns and connects, then builds a plan around their strengths. Learn more about [FASD and developmental delay](/fetal-alcohol-spectrum-disorder), and explore how [occupational therapy](/occupational-therapy) and [speech therapy](/speech-therapy) support young children across these areas.

## Trusted sources
The World Health Organization and CDC on fetal alcohol spectrum disorders and child development; the American Academy of Pediatrics and HealthyChildren on developmental milestones and global developmental delay in young children.

**Next step —** Concerned your child is behind in more than one area? Book a developmental screening, and let a clinician map the picture and the right early support.
