My kid is not listening to me anything how I calm him n understand him...??

A. First you understand why your child is not listening to you why your child is behaving like this you need to figure out the root cause and reason behind it then you can handle the situation monitor the behaviour of the child and also try to figure out where is your child learning all these things from a child to child the other partner or anybody else in the family and take support of them to talk to the child to understand why the child is not listening to you
