I am a step mom of 5 yrs.to a now 15 1/2 yr old who is ADHD/BIPOLAR I've known the child for 9 yrs so i've practically raised him. My problem is he is very defiant with only me he does not display any defiancy when his dad is around only shows his nasty side when dad is not home. We have had many of arguements here he always has to have the last word he does not listen to me he just does the opposite. Homework is a huge problem here thats where most of the issues stem from he has the school fooled. he does not like doing his homework and when the teachers ask him for it he always tells them he forgot it at home but the truth of the matter is he doesnt do it at all. at home we confront him and he tells us he misplaced it or he forgot it in school its an endless battle with home work. most days now he comes in from school and talks to numerous friends on the telephone talking about nintendo games ect. my son is a big fanatic when it comes to games we have taken the games from him in order to get any kind of homework done.His father believes that by giving him back his games that it will solve the problems here in the house hold. His dad does not discipline his son at all more or less leaves it up to me and now the child resents me. I'm at my witts end here if anyone can help I would welcome any input or help you can give.
