Step son is unhappy that his parents have separated and is now worse since his dad has moved in with me and my son, age 6. We know he is jealous and we try and arrange one on one time with him and his dad. Step son is now hitting on a daily basis if something doesnt go his way. Other children wanted to watch a different DVD than him so he hit them. He lost at tennis so he hits. someone cheated at a game, he hit them. We have tried everyting and we are now considering splitting up. need help x
