Little boy in the pool

Got Ken in the pool with Andrew for swim class today :-)  Seemed like Andrew had fun again and did some swimming by himself.  Our current challenge is getting him to keep his mouth closed so he doesn't swallow water and to put his legs up behind him to swim forward.  The latter stems from him grasping the treading water-concept like pedaling, but he looks like he's riding a uni-cycle in the pool.  haha
