While on vacation our kids swam just about every day. The boys mostly jump and dive in over and over and over again.
I realized after I downloaded the photos, how much everybody in the pool was just sitting there watching them...
Lilah also became very comfortable in the water. We put water wings on her and she was completely comfortable in the deep end, swimming back and forth between adults, doing little spins, etc.
In the kiddie pool she would lay on me tummy and "swim" with her arms. She was very proud of herself. Then she would lay on her back and try to float. She was "swimming" just like the big kids do.
