So these past 8 days have been rough baby only wants to sleep in my arms. I just put him down in his bassinet and he turned his head up like he wanted to turn so I put him on his belly to see what he would do. He fell asleep. Last week my baby was in the nicu for a couple of days and they had him on his belly sleeping under the lights. So this is what he been wanting. I dont feel comfortable letting him sleep on his belly. Any mama let their baby sleep on their bellies? From my understanding they suppose to sleep flat on their backs. Nicu definitely messed things up for me.
