Have watched this post with interest, Sorry can't watch the vid.
Making sure your kid's can swim is a great thing , it should be manditory here with our ocean ,swimming lifestyle,
BUT , he only reason children drown is because no on is supervising them in the water!!!!,
the rules for our pool are ,kids (they are all over 12 now) MUST be competent swimmers , or don't bring em over.
I just think that we have children , because we love them

, watching them %100 of the time they are in water is the only safe way to prevent drownings, especially the young ones.
