And parents: children playing in the water make noise. When they get quiet, you get to them and find out why.
Oh, man, absolutely.
Last year, for the first day or so of a visit to my brother's (in San Diego, and he has a pool), I thought that water wings were adequate. DS was in the shallow end, having fun, I was in arm's reach. My brother was doing laps, and he was at the deep end, and we were talking. I turned to my brother, and DS got quiet. I turned around, and the water wings had allowed his arms to go above his head as he sunk down into the water, and the wings wouldn't allow his arms to change position. AUGH!
It was so so frightening, and yes, DS was silent. I took off the water wings, DS was touching some part of me (not just in touching distance) for the rest of the time in the pool that day, and next day we bought a Speedo flotation vest and threw the water wings away.
And DS has been in swim lessons since last September. Not that that will make him tragedy-proof, but it's a better situation than last summer!
Oh, and I just talked about those tall lifeguard chairs at the Y's pool with DS. He didn't know why they were so tall. I guess I instinctively knew it, because I explained that they are tall so the guards can see *down* into the water.
