my 6yr old son is having very bad behavior problems and not wanting to listen to myself, his mother, and or his teachers. I took custody from his birth mom last May. i had alot of problems with him at that time but had got better. Put him in kindergarten this year and the school is having alot of problems with him. He will not do his school work. He will be up and down in his seat at school even when the teacher is teaching or talking to him. He has even got candy out of the trash can and eat it. He also talks about his underwear and things that a 6yr old shouldn't even know about (adult activity). that adult activity, he even goes to the extreme of shaking and even tring to show personal parts. The school is wanting to hold him back this year. They say he is to far behind in learning that he isn't ready to move to the first grade. I disagree with that because of this... The teacher can give him work to do in class that morning and he won't do it. The teacher will send it home for him to do. He sits for 3 or 4 hours untill i really get on him to do his work. We as the parents don't explain how to do the work at all. He will then do the work in about 5 minutes or less and it would be the right answers. So to me that tells me that he knows how to do things, but chooses not to do the work at all. Can anybody please help me with this problem in his behavior at home and school?
