Cindy - When we were dealing with early wakings (now DS sleeps all the way 'til 6am, most mornings!
), we took turns sleeping in on the weekend. For a while, my morning was Saturday, and his was Sunday. We still do that, sometimes. And one weekend, DP actually suggested I get a hotel/motel room for the night! I was so exhausted, and so used to waking at 6am, that I really didn't get more, or better, sleep... but it was a really nice gesture.
Since we're all up at 6am, M-F (DP leaves for work shortly after 7am), there's also usually a night when one or both of us goes to bed early (8:30-9pm), just for sanity's sake.
