Please give me some advice on how to make your baby laugh.

The time when a baby laughs is morning and evening. My baby started laughing at two months old. At first he laughed and screamed, and later he laughed. The time when a baby laughs is also different. It depends on the situation. My baby usually laughs when I sing; when I dance; when grandma squats on the ground to pick vegetables; when she covers her face with a cloth and then takes it away. Don’t worry, each baby starts to laugh at different times. Same. My baby can only now laugh.
