We are in the same situation. #2 is due next month. Dd is 26mos now. We have moved her out of the nursery into a 'big girl' room (last weekend, in fact), but decided to leave her in a crib. She is quite content in the crib, plays in there happily after waking, and has never tried to climb out (knock on wood). We had planned on buying a new one, but were lucky enough to be able to borrow one.
