Global Developmental Delay at 18–24 months shows as a pattern of delay across two or more areas at once — late or unsteady walking, very few words, limited following of instructions, little pretend play, and trouble with spoon-feeding or stacking. A single late skill is often normal; a pattern, or any loss of skills, is worth a screen.

*Every toddler grows on their own clock — but when several skills lag together, gently and steadily, it is worth a closer look.*

## In short
Global Developmental Delay (GDD) means a young child is significantly behind in **two or more** areas of development at once — such as movement, talking, understanding, play and self-help. Between 18 and 24 months, watch for delays that span several skills rather than one. Noticing early is a strength, not a worry — it opens the door to support that genuinely changes the path ahead.

## Signs worth watching at 18–24 months
**Movement (gross & fine motor)**
- Not yet walking by 18 months, or very unsteady, frequent falling
- Difficulty climbing, squatting to pick up a toy, or holding a crayon
- Not stacking 2–3 blocks or feeding self with a spoon

**Talking & understanding**
- Few or no clear single words by 18 months; no two-word phrases approaching 24 months
- Doesn't follow simple instructions ("give me the ball")
- Limited pointing to show or ask for things

**Play, social & self-help**
- Little pretend play (feeding a doll, talking on a toy phone)
- Limited interest in other children or back-and-forth games
- Not imitating everyday actions like waving or clapping

**Always act promptly on** any *loss* of skills the child once had, at any age.

## The science, simply
"Global" means the delay is across the board, not in one area alone. At this age a single late skill is often normal variation — but a *pattern* across domains, especially with parental concern, is a clear signal to screen. The earlier the brain's most adaptable years are supported, the bigger the gains. This is screening, not labelling — many children catch up beautifully with the right help.
