They keep me rollin'...

When I picked Jack up from daycare today his teacher said that he had been rolling over!!  He has been trying too at home,  but getting stuck on his shoulder.  She said that he did it once and then kept doing it any time he was on the floor.  Of course,  when we got home he wouldn't do it.  I had better be ready,  he's going to be on the move before I know it!
