When Do Babies Start Laughing?

Your baby’s first year is filled with all types of memorable events, from eating solid food to taking their first steps. Each “first” in your baby’s life is a milestone. Each milestone is an opportunity for you to make sure your child is growing and developing as expected.

Laughter is a wonderful milestone to reach. Laughter is a way your baby communicates that you can understand. It’s a sign that your baby is alert, intrigued, and happy.

Read on to learn about the average timeline for babies to start laughing and what you can do if they miss this milestone.

When Should Your Baby Start to Laugh?

Most babies will begin laughing around month three or four. However, don’t be concerned if your baby isn’t laughing at four months. Each baby is different. Some babies will laugh earlier than others.

4 Ways to Make Your Baby Laugh

Your baby’s first laugh may happen when you kiss their belly, make a funny noise, or bounce them up and down. There are also other techniques to draw out a laugh from your little one.

Funny Noises

Your baby may respond to popping or kissing sounds, a squeaky voice, or blowing your lips together. These auditory cues are often more interesting than a normal voice.

Gentle Touches

Light tickling or gently blowing on your baby’s skin is a fun, different sensation for them. Kissing their hands or feet, or “blowing a raspberry” on their belly may elicit a laugh, too.


Objects in your baby’s environment, such as a zipper or bell, may seem funny to your baby. You won’t know what these are until your baby laughs, but try using different noise makers to see what makes them laugh.

Fun Games

Peek-a-boo is a great game to play when children start laughing. You can play peek-a-boo with your baby at any age, but they may not respond by laughing until they are four to six months. At this age, babies begin learning about “object permanence,” or the understanding that something exists even when you don’t see it.

If They Miss the Milestone

According to many milestone markers, babies typically laugh between months three and four. If the fourth month comes and goes and your baby is still not laughing, there is no need for concern.

Some babies are more serious and don’t laugh or cackle as much as other babies. This might be OK, especially if all they’re meeting their other developmental milestones.

Focus on the entire set of age-appropriate milestones, not just one. If, however, your baby hasn’t reached several milestones in their development, it’s worth speaking to their pediatrician.
