My LO is around the same age as yours and she wakes at around 430-530am most days. This doesn't bother us as we get up at 5am anyway. Generally though I will just either leave her to talk to herself in bed for half hour, then get her up & changed, or get her up & let her play in her walker till I'm ready for her first bottle (usually from 5 - 530 I make lunches, empty dishwasher, feed dogs, etc). DD will normally go down between 6 & 7pm each night. I don't know whether she wakes up during the night, but if she does she doesn't disturb me!! All I can suggest is maybe try leaving him there for a bit longer or try to darken his room as much as possible. Otherwise, enjoy the extra few hours you have in your day ;-)
