My heart goes out to the Al Geiberger family. There is no explaining away the death of a 2-year-old child by drowning. But, if anything can come from such a tragedy, it would be to shock all parents of toddlers into action.
As a professional swimming instructor, I have taught dozens of 2-year-olds (and younger) how to swim. They are fully capable of saving themselves, and they actually enjoy the water.
There are learn-to-swim programs available everywhere, I urge all parents to make their children water safe now.
