when do infants start to laugh: Development of Laughter in Babies

Curious about when infants start to laugh? Laughter is a milestone in a baby's development, signaling their growing cognitive and social abilities. This delightful sound marks a significant step in their emotional journey and their ability to connect with the world around them.
Infants typically begin to laugh around **4-6 months of age**. This milestone is not just a sign of joy but also a significant developmental marker. While every baby develops at their own pace, laughing around this timeframe signifies a baby's brain is developing and maturing.

Before 4 months, babies might produce sounds that resemble laughter, but these are often involuntary reflexes. However, around 4 months, babies begin to laugh in response to external stimuli, like a playful tickle, a funny face, or a familiar voice. As their brains develop, they start to understand the concept of humor and find joy in playful interactions.

The development of laughter goes hand in hand with other important milestones like social smiling, cooing, and babbling. These abilities all contribute to the development of a baby's social and emotional intelligence. As babies laugh, they learn to connect with others and build relationships.

It's important to remember that every baby is unique, and there's a wide range in when they reach milestones. While most babies start laughing between 4-6 months, some may start earlier or later. If you have any concerns about your baby's development, consult your pediatrician. They can assess your baby's progress and provide personalized guidance.
