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.

What Makes Babies Laugh

Tried and true ways to get those giggles going

Physical Play

  • Gentle bouncing on lap
  • Flying through the air (safely held)
  • Tickling armpits, feet, or tummy
  • Gentle raspberries on tummy
  • Swooping motions

Silly Sounds

  • Pop sounds with your lips
  • Exaggerated sneezes
  • Animal noises
  • High-pitched silly voices
  • Kissing sounds

Visual Games

  • Peek-a-boo (classic for a reason!)
  • Funny faces
  • Hiding behind objects
  • Popping up unexpectedly
  • Making objects 'dance'

Anticipation Games

  • 'I'm gonna get you!'
  • Building up to tickles
  • Counting down to action
  • Chase games (crawling age)
  • The pause before the pounce

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!
