> My wife and I sleep on the floor, with a few blankets, and have slept with our daughter between us since day one

And when your daughter is old enough to talk, she'll tell everyone she sleeps on the floor, and CPS will come take her away (this sort of thing is a major fear of mine -- some minor idiosyncrasy or eccentricity will be taken out of context and misinterpreted as a sign of an "unfit" home, and they'll come a-knockin').
