Whenever I put my 7 month old baby down to sleep in his sleeping bag he will lay on his side or his back. When I put him down for a nap during the day without his sleeping bag he always rolls over and lays on his front. As I am not in his room I always have the baby monitor with me. I go upstairs and turn him on his back. I wait and then he then goes into the tummy position and then stays there. I never let him fall asleep naturally in the tummy tummy position. As I am scared of him not being able to breathe. So what should I do to help him ?
