i have recently taken in my nephew who was in a bad situation. when he arrived he was the perfect child, always looking to please us. after a couple months of living with us he has started peeing in random places...... on the floor, on my son, out the window, outside, etc... he has also started mooning and showing his privates. he has gone as far as pulling his pants down and another little girl pulling her pants down and him on top of her. he comes from a physically and mentally abusive home, and i have him in therapy every week. he is also diagnosed ADHD and mood trait disorder. i have tried everything to get him to stop these behaviors. he has written sentences about appropriate behavior, sitting in the bathroom, spanking, grounding, discussions, rewards, etc.... PLEASE HELP!!!!
