Rolling from back to tummy!

I can't believe how fast Aaron figured out rolling from his back to his tummy just after a few days he could roll from tummy to back. Now we really have to watch him closely even when he's taking a nap. I was preparing dinner when he was napping this afternoon, I went back to check on him after a few minutes and found him sleeping on his tummy on the other side of his sleeping mat. We better get a safety gate soon because he is already rolling all over the place. My munchkin is truly growing up too fast!
