Thanks Ann. I think we're going to try putting our older daughter in our room during the transition. Hopefully it'll work alright, DH goes to bed an hour earlier than DD does when he has to work the next day, then has to get up at 4:20am. It's really the only option though, so we'll see how it goes. Our house is pretty small, just the two bedrooms and living/dining/kitchen area (and bathrooms of course). If she does wake up when DH does, she can just curl up in bed with me and go back to sleep.

Thanks again for the input!
