How did you handle sleep when the baby came?

I teach, so during the school year I'm up at 5 am and asleep by 10 pm. My husband works on west coast time so he doesn't wake up until 10 or 11 am and goes to bed between 1-3 am. Waking him up any earlier than 10 am is a nightmare.

During the week, I don't see it being too much of an issue. On the weekends, on the other hand, he won't get out of bed til noon. It already annoys me pre-baby because I feel like we waste so much of the day waiting for him to wake up. I worry I will really resent it when LO gets here.

Does anyone else's SO try to sleep all day? How do you handle it? Did you try to force him/her to wake up earlier? Did you just take the baby to do things alone?
