We turned away for what only seemed a minute and he was going under. He was slightly blue in the face when the life guard brought him out.
The weird thing is he didn't fight or flail. He just sort of faded away into the water, and it struck me as especially weird that he didn't seemed scared at all after.
It has haunted me ever since just how easy it can be for a child to drown. Many swim lessons for my child later, I still watch him like a hawk and insist on life jackets in any moving water conditions.
Bondi Rescue, a series on Netflix about a team of Australian lifeguards, is instructive and entertaining.
