has he always done this cathy ,my man is always sleeping early although he does try to stay awake later he is up from 4 in the morning ,in the holidays he does the same but think this may be due to the fact that this is the time he is used to sleeping ,we also don't get up till late but i don't know if he has been awake since his normal time or not ,if it is worrying you then ask him to see a doctor but i really don't think there is anything to worry about
