WEST PALM BEACH, Fla. (AP) — In an airy indoor pool with fish cutouts on the walls, a group of small children bobbed, floated and tentatively flutter-kicked.

It was what it looked like, a starter swimming class. But here, instructors worked one-on-one or even two to a child. Some held cards to help kids communicate with teachers by pointing instead of speaking. No one blew whistles.
