Do you really have to discontinue use at 15 lbs? That seems so crazy when the RnP is 25 lbs. Currently we start our DS out in the PNP Bassinet in our room. After he wakes to feed (just once per night around 3 am pretty consistently) he often doesn't want to go back in it so then I use the RnP until I have to wake him up to feed him before work around 6:30. He has his 4 month appointment on Thursday so then I'll find out for sure how much we weighs, and I'm pretty sure he is over 15 lbs...but the PNP still seems to fit him just fine! I'm really not quite ready to have him out of our room and in his crib. What are others doing?
