Looking for advice. I have a Rock n' Play that my newborn has been sleeping in, when I put her in the crib shes waking up every hour, When I let her sleep in the rock and play she sleeps for 2-3 hours. Is it safe to let sleep in it? Shes next to my bed and I also like that a lot having her that close to me. Anyone else let their little one sleep over night in a rock and play?
