Thank you for all the responses everyone! I love this community because you are all so nice and helpful!
I'm going to keep trying to get him on his back but his head control is amazing for his age so hopefully he starts rolling/holding his head up early so i can stop stressing about it. I guess the rnp is just where he will sleep till he starts sleeping on his back or he gets head control/rolling skills.
