Our little girl is 14 weeks and she has been sleeping at night in her rock and play until she stared to attempt to roll on her side in it. We she moved her to the crib and now it has me nervous! She rolls on her side as soon as I lay her on her back.  The pediatrician said its ok but I am always waking up paranoid. Does anyone have the nighttime monitor that they put on the baby? I wasn't sure if I should even take that route.
