Many of the events in your child’s life don’t feel so eventful as the first step, or the first time he says clearly “mummy”; but they’re important signs that your baby is growing in front of you.
One of these events is the moment in which he develops his sense of humor and starts laughing in response to something he finds funny.
This usually happens around 3 or 6 months old. In these first moments, laughing is the response of a super active stimulus (a kiss or blow in a bare belly),
but once they are older than 6 months, they begin to laugh in response to more sophisticated stimuli.
When you laugh at your baby, you are helping him to develop his social skills.
