Two of my kids who are now 24 and 26 received similar training when they were 8 months old. We lived in Florida and had a pool so there was no way we were going to leave anything to chance. I recommend checking that out for anyone who has toddlers and a pool!
A great thing to have children learn. Does it seem to you they are as interested in making money as teaching? It seems if they were truly interested in "eradicating drowning children" that they might tell us how to teach the basics to our kids.
