my child has 4 years he didn't sit on his seat at school is this any serious how to sit my child on school pls give me instructions

A. Kids are hyperactive in nature in this age and also they are not used to sitting in a new place for a longer time which is normal slowly your child is going to learn to do that the child needs regular counselling and the school people need to have little bit of patience and over the period the child will learn it you just have to teach your child when you go to the school follow the instructions given by your teacher try to sit in a place try to develop an interest in the child doing all these things
