If you created an incline where your baby sleeps, how did you do it? Our ped wants us to start laying C down this way since he screams when we lay him on a flat surface to sleep at night.

He's 7 months old and over the weight limit for his swing and the top of the PNP, and can sit up well enough to catapult out of the RNP, so the kid has gotta learn to like his crib.
