I'm gonna echo englishchick when baby naps you nap. And I'll add don't worry about having the house spik and span. You need to get your rest. I remember years ago a couple of times that the store would call me at 4am to ask me to fill in on a 7am shift, I'd say yes, hand up the phone, wake up at 7:30 to another call asking me where I was. I had no recollection of the first call.
