Michael Phelps gives son Boomer a swimming lesson

Michael Phelps is wasting no time getting infant son Boomer acquainted with swimming pools.

The 23-time Olympic gold medalist accompanied Boomer to swim practice Monday at Baltimore's Meadowbrook Aquatic and Fitness Center, where Michael also trained as a kid. Boomer apparently wasn't a fan of the water, though.

"He put his face in and didn't really like it too much," Phelps said. "Now he's just grabbing on for dear life."
