So my MIL got us the Graco pack n' play with the napper/changer attached so baby can sleep in our room the first couple of months or so. It just occurred to me that the napper part doesn't seem to be "SIDS approved"... aren't you supposed to lay them in the middle of a crib with nothing else, even bumper pads? Am I just being overly cautious? I can't imagine Graco would make something, call it a "napper" which to me implies the baby should SLEEP there, and have it be unsafe. But maybe? Thanks, ladies!
