I am house wife of 32 years old in a joint family. I have son of 6 years old. He is average in studies. Problem is that he is very naughty and over hyper active. When he concentrate in studies he brings outstanding result. But he used to beat and irritate everyone, specially his 2 year's younger sister. He doesn't listen to me. Very aggressive. Sometimes I used to cry, but he doesn't show any sympathy. His mostly time pass is mobile and TV. Please suggest me how to handle him. He is single male child in our full family. I am very much worried about his future. please guide me.
