Anyone elses LO nap face down on them? He's breathing but his face is in my shirt or on my skin.

During nap time he always rubs his face. On his back he uses his hands and wakes himself up. On me, he does this.

Night time he will sleep on his back, swaddled still,and always watched. I know he should have hands out but he shows no signs on turning.

11 weeks tomorrow. Any suggestions? An allergy maybe?? He always tosses and turns due to gas.
