my son is 5 year old he keeps laughing for no reason if I tell also he won't he will do it more..... what should I do

A. A lot of kids behaved like this but over the period of the behaviour is increasing like this then that is not good I suggest you to kindly talk to your child in confidence to understand why does your child keep doing it you should tell me why are you laughing I will also laugh with you then we’ll have a company laughing instead of correcting your child try to figure out what is the reason behind it
