Yes! My mom started me out in "drownproofing" type classes when I was a baby, and I swam in classes all throughout my childhood. I enjoyed it so much, that I swam competitively when I was in high school; I love to swim! If I every have children, they will definitely be placed in "drownproofing" classes as babies, so they can learn how to swim and roll onto their backs at a very, very young age.
There have been several toddler deaths in my area recently that were really heartbreaking and preventable. I think it's so important for people to learn how to swim, regardless of age.
