Ethan Vo, 3, of St. Petersburg practices putting his face in the water Monday during a swimming lesson with Joanne B. Walker at St. Petersburg's North Shore Aquatic Center. Walker, of Mrs. Walker's Swim School, has been teaching swimming locally since 1968. Walker said that each time she hears about another drowning it "rips my heart out, because there's no excuse for it." But she cautioned that teaching children to swim would not stop the toddler drownings. "Parents need to stop socializing and supervise their children," Walker said. Supervision and prevention is the answer for children 4 and younger. "And don't put in a pool until your children know how to swim," she said. Walker teaches part of the year at North Shore and, in the summer, at Fossil Park Pool.
