America's iconic swimmer Michael Phelps and son Boomer, four, figure in a video which teaches kids how to stay safe in water.

In the 30-second PAW Patrol Safety First video, Michael, Boomer and other parent-child pairs take users through the "ABCs and 123s of swim safety" that include never getting into the pool without a grown-up, locating the shallow and deep ends of the pool and learning how to swim.
