This little man of ours has been playing possum with us! He has been happy, happy on his back and only rolling over to his tummy occasionally. I never find him on his tummy in his crib and I was starting to think that it was strange. Today I figured out why I never find him on his stomach. He can roll to his back. And judging by the speed that he flips back over, I think he has been doing it for awhile. I'm going to keep an eye on you Ollie boy!
