Try this cute trick. Ask a toddler how big he is. When he lifts his hands, they’ll only reach the top of his head. It’s adorable, but it makes it tougher for the little guy to propel his head-heavy body through the water than it is for an adult, even one who isn’t a world-class swimmer. Ask your child to lift his arms straight up. The farther they extend beyond the top of his head, the closer to an adult’s his body proportions—and his buoyancy and maneuverability in the water—are likely to be.
