I'm fostering a 12 year old boy with ADHD/ODD/Conduct Disorder. He does not follow rules - frequently breaks rules. He was removed from his birth mom's home a year ago. She is a single parent, smoker (cigarettes/marijuana), alcoholic, and drug user. She did not supervise the child or enforce any rules... Can this boy be taught or trained to follow rules? If yes, how to do so? Note - He hangs around with troublemaker friends. I'm thinking it might be best for him to be moved to a different area/school - away from those "friends"?
