If you are using the PnP for sleeping or even for playing... It says that the bassinet can hold up to 15lbs. DD is pushing the edge at 14.6lbs and we are looking to move out of the RnP (not ready for the crib in another room yet) and into the PnP. We borrow a portable crib from my mom and tried it out last night but I feel like the PnP would work equally as well and we wouldn't need to purchase another piece of baby gear.
We use the top level often for naps and as a little play area when we need to get her off the floor.
Have you all been using the top section beyond 15lbs? STMs? I mean, I guess we could just drop it to the bottom, but it's a lot easier to grab her and I obviously don't want to compromise her safety if the thing will collapse because of weight.
