While your baby will make noises 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 smiling spontaneously at people. Once your baby masters smiling and can recognize the positive reactions, sound effects like cooing will begin. Cooing will turn into giggles, and soon after, you will likely hear your baby's first laugh.

If your baby smiles spontaneously but doesn't seem to want to laugh, you might worry that you're doing something wrong. Don't forget that every baby is born with different innate temperaments, which could influence how much your baby wants to laugh.

The first few months of your child's life is an exciting time, and each milestone brings up a whole range of emotions for you as a parent, from your baby's first words to the eruption of their first teeth. Waiting for your baby's first laugh can be frustrating, but remember, the wait is worth it!
