Our summer swim experiment was a success, by the way.
Casey, who'd worked his way through five previous swim program/schools and was terrified of any water over 3 feet deep can now swim. In 8-foot-deep water. By himself. After jumping in the pool. Even if no adults are in the pool with him.
Marcie still needs a grown up in the water, but she, too, loves jumping in, and can swim pretty far without even taking a breath.
I admit it. We're impressed. With the kids, too-- but especially with their swim teacher.
