If your tot takes to water like a guppy, it may be time to sign up for swim classes. But before you do, it’s important to understand that swim classes for babies and toddlers aren’t designed to teach little ones how to swim on their own. They’re meant for kids and parents to be able to have fun together, safely, in the water.

That said, there have been a few studies supporting the benefits of swim classes for toddlers — some even suggesting that when a young child takes one with a parent, her risk of having a drowning accident may be reduced. It's definitely a compelling case for signing up your child sooner rather than later.
