FTM here. My three month old is rolling over. She can roll over from back to front but not from front to back yet.
The problem we have is that she likes to roll over in the middle of the night and gets stuck. Instead of turning her head to the side and going back to sleep, she rubs her face in the mattress and gets upset. She can lift her head up so she can breathe, but she has been waking up at 4-4:30 instead of her normal 6:30-7.
