Waiting for your baby’s first big laugh can be both exciting and frustrating. If you haven’t heard it yet, here’s how you can make your baby giggle or laugh for the first time – and you’ll remember it forever. While your baby will make sounds and some facial interactions from birth, a social smile will begin to develop around three months of age.

By four months, your baby will start spontaneously smiling at people. Once your baby learns to smile and can recognize positive reactions, sound effects such as cooing will begin. The cooing will turn into a giggle, and soon after that you will probably hear your baby’s first laugh.

If your child spontaneously smiles but does not seem to want to laugh, you may be worried that you are doing something wrong. Don’t forget that every child is born with different natural temperaments, which can influence how much your child wants to laugh.
