Hello! Hopefully this makes sense...

My LO is 5mo and has been rolling over both ways for about a month. He has been a great napper and we have almost mastered the putting down "sleepy but awake"

However, this has all gone to h*** now. As soon as I place him in his crib he rolls over and hates it. It's like his body won't let him be on his back. He has always disliked tummy time and just screams while on his stomach. I'll go in and roll him over to his back but 5 min later he rolls over and starts screaming again. I don't think he would ever sleep on his stomach but seems to have a huge problem staying on his back. Is there anything I can do to prevent him from rolling over? Help!!
