Since my son was 4 months old, he started preferring to sleep on his belly. He would still occasionally sleep on his back without fuss but now anytime he rolls over onto his back he wakes up instantly and screams. We also can’t lay him down on his back to sleep or he screams until we flip him onto his belly. He can roll to and from his back so that’s not a problem but has anyone had this issue? He wakes up about 4-5 times a night screaming because he rolled onto his back
