Mattie is quite a little swimmer. Here is a video of her diving into the deep end of our pool. She said that her Nonna (Bubba's mother) taught her. You'll hear Bubba asking her to use her float. I'm not sure if she hears him or, more likely she just wants to keep swimming. I wish we had some video of her under water. She actually swims down to the bottom of the pool, in about 4 feet of water, to retrieve pool toys. If she dives in she'll get them at 6 feet!
