What Mary can do at the pool

We took Seth to the Rio Rancho outdoor pool (best one here) on Thursday, and we had such fun.
Mary is now (on her own) holding her breath, and going completely under the water! She also went off the slide and held her breath under the water, but it freaked her out too much to do it more than one time. This is a really big thing for her, and she is now asking to swim too, so the next order of business is to find swim lessons in the fall.
