My Son has started rolling over in his sleep and winding up on his belly, should i be turning him back over on his back or just let him sleep? He has really good head control and can move it very well. The only thing is he can't quite figure out how to roll from stomach to back. I am a first time mom and i am just concerned with the whole SIDS thing. I leave him on his belly while i am up but when i go to bed i place him on his back and when i go in to check on him through out the night he is on his belly and i flip him again. Just a concerned mom i guess, any suggestions or advice would be greatly appreciated.
