I just put a brick under two of the legs. He hardly noticed, but I had to wake throughout the night to make sure he hadn't slid down and sideways against the bottom edge. We also did this with his crib. It helped alright for about 2 weeks. But then we ended up going on Zantac, and put the bed back to flat.
A rolled up towel under one end. I also have the RNP which DS loves but I am transitioning him to the PNP right now because daycare is not going have the RNP. He is doing well taking his naps in the PNP.
Re: if u put pack n play at an incline...how??
We have the arms reach co-sleeper and I lifted the mattress and put a rolled up small towel under the top portion. So the head rest is on an incline.
That worked for a couple days and now back to hating it again. Think I am getting RNP today!
