hi my baby boy is three years six months active boy. Today for first time he hit someone kid in school. Actually there is another kid who hit mostly everyone in the school including my boy. M thinking it's the reason my boy hit someone else. But he did it as they fight for a toy. And I found this behaviour in my child this month. but he never did it in school. Today for the first time I found this behaviour of my kid. he normally can't explain everything yet he speaks. still he never explain things properly. How do I make him understand that not to hit anyone?? What should I do??
