When Do Babies Laugh?Timeline & How to Get Those Giggles
That first real laugh is pure magic. Learn when to expect it, what makes babies giggle, and how to keep those belly laughs coming.
The Short Answer
Most babies start laughing between 3-4 months old, though some may begin as early as 2 months or as late as 6 months. First you'll see social smiles (around 6-8 weeks), then cooing and giggling, building up to those full belly laughs by 5-6 months.

Tips for More Giggles
🎭 Be Theatrical
Exaggerate your expressions and sounds. Babies love over-the-top reactions—your normal speaking voice won't cut it!
⏰ Time It Right
A well-rested, fed, and content baby is most likely to laugh. Overstimulated or tired babies won't find anything funny.
🔄 Repeat Repeat Repeat
Unlike adults, babies don't get tired of the same joke. If peek-a-boo works, do it 50 more times—they'll laugh every time!
📱 Capture It
Keep your phone handy! First laughs are fleeting and you'll want to remember them forever (and share with grandparents).
👫 Involve Siblings
Older siblings are often the best at making babies laugh. Their energy and unpredictability are comedy gold.
🎈 Build Anticipation
The pause before the "boo" or the countdown to a tickle is often funnier than the action itself!
