So the rock n play.....

Soooo many moms are telling me this is a must have. So many moms are telling me their babies sleep in it overnight. These were not around with my first 3 kiddos. I'm pregnant with twins after 2 losses so honestly, I'm a little more protective than I've been before. Are these safe for nighttime sleep? According to standards set by AAP, the answer is no. But I mean, neither are trampolines and my kids use those. My vote is not to use them because I just don't know if it's worth the risk. So have any of you discussed these with your pediatrician? What have they said? I'd love to hear your thoughts.

Oh and I'm not worried about them rolling in it or anything. It just doesn't meet the requirements of a flat & firm surface. Thanks!!
