My baby, 4 months old, can roll over without a problem from his back to his belly. But he can't go from his belly to his back. I thought this was completely normal, but his doctor told us the other day that usually babies start off rolling from tummy to back. Then around 6 months is when they can go from back to tummy. I'm not worried about anything and neither is my doctor, I was just curious if any of your babies can roll back to tummy and not tummy to back. Picture just because.
