Luke's really taken to the water this summer. It's probably because he's tall enough to stand up comfortably in the shallow end. He's doing lessons for the first time, too. He started at Level 1 on the first day but quickly was sent to Level 2 because he was too skilled (i.e. he could put his face in the water, jump in, and didn't need to use a bubble on his back to hold him up). Today, he even got to go to the semi deep end to give treading water a try.
