It's just too early

What does a person do when they're on a totally different sleep pattern from their spouse? Alif is up early every morning, whether he fell asleep at 8 or 12 the night before. I, on the other hand, would like to sleep until at least 6:00. I've asked him to just keep quiet until 6, but it's like he's simply driven to move, and by 5:30 he's just got to be up and around. The simple solution seems to be that I should just go to bed earlier and make good use of this early morning, but after a long day with my adorable kids, I relish the quiet, late-night hours. Don't get me wrong, I'm not up really late - I'm usually in bed by 10. What to do, what to do?
