Absolutely the best way to teach kids to be safe in the water, and swim at a young age. People are always amazed that our 3 yr old isn't wearing "floaties" or other "lifesaving" devices, but rather she swims, and can do a lifesaving float at any time if needed.
PM me if you want more info. It is the best!
Too bad future generations aren't here to see all the great things we are spending their $$ on!!
