He rolled over!!!

Mason rolled from his belly to his back today. I didn't see him do it the first time...I had him on his belly and then I looked back and he was on his back! I didn't believe it, so I put him back on his belly and he did it again! I think it scares him though because he will roll over and then cry...like "Help me!" It is so cute. He has been doing it all day...and of course I have been doing nothing except watching him roll over all day! He is only 2 months and 1 day old and he is already growing up too fast!
