Laughing

That first real laugh is unforgettable. Around 4 months, babies start laughing out loud — a sign of developing social awareness and emotional expression. Laughter shows your baby understands surprise and anticipation.
Signs to Look For
- ✓Laughs out loud when tickled or surprised
- ✓Giggles during peek-a-boo or bouncing games
- ✓Squeals with delight during play
- ✓Laughs in response to funny sounds or faces

Every child develops at their own pace. However, talk to your doctor if you notice:
- •No laughter or vocal delight by 6 months
- •Rarely makes sounds or seems disengaged during play
- •Doesn't respond to playful interaction
