Jamison fell into the pool twice. He often reminds of this by saying - I went under! - and no matter where we are or what we're doing we know exactly what he is talking about.
Ruthie, on the other hand, does know how to swim. She wore her floaty life jacket in the pool but I'm not sure it was necessary for her. She swam around for over an hour one afternoon - just in circles, with no goal in mind. Jamison thought she was amazing when he would throw in a ball and she would swim after it and bring it back to him. I think Kristen and Mark need to find a toddler water polo team in Nashville.
Maddie is a more finicky swimmer. Yes, she can dog paddle but it will only be on her terms and there better be an adult immediately next to her. She enjoyed the hot tub-turned-kiddie-pool. (Ignore her eye. She had a weird thing going on in which her eye swelled up only in the mornings)
