My son has really bad behavior
My son will be 6 next month, he is in kindergarten this year, and he is very bad every day. At school he hits kids, is disrespectful to his teacher and yard duties, he steals from his classroom or his friends. At home he is just as bad he doesn't listen, he picks on his brothers and I have a very hard time with him. I’m his step-mother and he's been this way since before I met him, I know he is a sweet kid, me and his dad and his grandparents have tried everything to adjust his behavior is there any advice that anyone could give me either just tips to help with his anger or even counselling options.
