I have a five year old boy. He has resorted to talking back, not doing anything he is told, telling you NO when you ask him to behave, harming his little 3 year old brother on purpose, urinating in his closet, on the toilet, floor, and wall just because. When put to bed at 8 pm they sleep in bunk beds they dont go to sleep until after 11 pm. Steeling food, getting up at all hours of the night to watch tv. I just want to know if this is normal.. Please Help
