On our trip Kodi got to swim almost every day.  Turns out she is a little fish.  When she has her floaties on she can go where ever she wants to with out any help.  In fact, she would rather no help at all.  She also learned how to go under water all by herself.  Once she had that down, she bobbed in and out of the water the whole rest of the time.  After spending so much energy though she had to take a rest.
