Twas hilarious really - I laid him down on a mat and everyone was oohing and aahing at him. He pushed himself up on his hands so his whole upper body was off the mat, lifted his legs up so his body was curved like a banana (!), then leaned to one side and rolled right over!!! I was glad I had witnesses because I'm sure nobody would have believed me otherwise
Bet he doesn't do it again for months now!!
