Yup, he has had his schedule set since he was 6 months old. Now he actually asks to go to bed ~1930 and gets upset if he get woken up before 0500. His older step brother gets to stay up till 2100 but from 1900 on no TV, no games just reading or playing in his room with his toys. We enforce this when he is here but obviously we cant control him when he is at his dad's place.
