My son is 6 months old and he rolls on his belly all day long. He loves rolling all over. He sleeps in his pack n play in my bedroom but I don’t go into the room right away since he goes to bed early. I watch him on the camera. He started rolling onto his belly while he sleeps and he doesn’t turn his head so he would be face first. My husband and I caught it every time but now one of us needs to be awake all throughout the night because we are scared he will suffocate. My biggest fear. He is able to turn his head to the side and lift his head during the day while he’s awake and doing floor time. But during the night he’s sleeping so he just rolls over and doesn’t turn his head. What should I do? Any advice?
