Early signs of Global Developmental Delay at 3–6 months

At three to six months, a baby is just beginning to reach, smile and find their voice — so the question many parents quietly carry is whether what they're seeing is simply their child's own pace, or something worth a gentle check.

In short

At 3–6 months it is too early to label Global Developmental Delay, because babies grow at very different rates. What helps is watching how your baby is moving, looking, listening and connecting — and bringing any persistent concern to a routine developmental check. Most early differences are simply variation, and a quick look gives reassurance or an early, helpful start.

Gentle things to watch (3–6 months)

These are patterns to notice over time, not a diagnosis — and one item alone usually means little.

Movement & posture

• Head still flops markedly and is not steadier when held upright by ~4 months
• Body feels very stiff or very floppy when you lift or hold them
• Not bringing hands together, or not reaching for a toy by ~5–6 months

Looking & listening

• Not following a face or toy with their eyes across the midline
• Little reaction to loud or familiar sounds, or doesn't turn toward your voice

Connecting & communicating

• Not smiling back at you (social smile) by around 3 months
• Very little cooing, babbling or vocal play; rarely seeks eye contact

Always mention promptly

• Loss of a skill the baby once had
• Persistent feeding difficulty, or your own steady worry — parent instinct matters

When a check is helpful

"Wait and see" is fine for a single late milestone in an otherwise thriving baby, but bring forward your routine review if several signs persist together, or if any skill is lost. A check now is about support and reassurance, never about labels.
