I have a son who gets an attitude every time you ask him to do anything. If he doesnt get his way. He stomps off or yells at people. I am the only one he doesnt yell at. We have grounded him, taken away all cartoons, game boy, play station. All the things he enjoys. I dont know what to do. If someone does something to him he cant let it go. Yesterday he brought up something that happened in school back in May. A boy caled him a name. I dont know what else to do. Any advice.
