We sleep in a queen-size bed. Given that we've been married for twelve years, I know this is not a shock to anyone. Buttercup is transitioning out of the queen-sized bed. That might be somewhat more of a shock, but we keep a family-bed concept going for the first couple of years and then move them to their own space (or more likely, space that they enjoy sharing with a sibling.) Most nights, the queen-size bed is fairly comfortable for the three of us: all have enough room and covers; we're cozy and warm without being crowded.
