I have a 7yr old son (middle child) who's behaviour is deteriorating by the day. Basically he thinks he knows the answer to everything. If he asks a question and you give him the answer, he says 'no it's not.....it's such and such'. He refuses to do things like homework and it takes things like his xbox being taken away for him to give in and do it. He is extremely stubborn, argumentative and fairly aggressive both verbally and physically. He's losing friends as he's so bossy and such a 'know-it-all'. He is very intelligent but his handwriting is appalling...more like a 4-5yr old and when we speak to him about it he says writing is boring and I hate it. He aggravates his older sister and younger brother almost for fun. He seems to enjoy it. When I tell him off and tell him to go to his room, he shouts at me and sometimes lashes out. Othertimes he cries at everything (usually things that aren't important). His teacher has had to speak to me several times about his behaviour in the classroom, shouting out, not sitting still. It doesn't matter how he is punished, nothing really bothers him. I am really at my wits end. Surely this isn't normal behaviour for a 7yr old. He is very different from my other children. I am beginning not to like being around him as he just causes everyone to argue. It really is getting me down and I don't know who can help me.
