Learning to Roll Over

E normally does not like tummy time at all.  We were lucky to get him on his tummy for more than 2 minutes without him bursting into tears.  This weekend something happened.  He has decided that tummy time isn't so bad after all.  I think it is due to the fact that he is getting stronger and can push himself up on his arms to look around and see the world from a new perspective.  He has also started to figure out that he can roll over from his tummy to his back.

It seems every time I have the camera out to capture him rolling over, he either does it before I can turn the camera on, or decides he doesn't want to do it.  This afternoon I almost got it, but he got stuck...
