My daughter (age 2) is like a fish, loves the water, doesn’t mind being dunked in the bathtub, and will happily and readily stick her head underwater to blow bubbles. She might be okay if someone tried to teach her to swim via this method. (Although said person would decidedly NOT be okay once he/she was within arm’s reach of yours truly, but moving along…)
Whatsit Jr. (age 4) is a little more nervous about the water. He likes playing it but flatly refuses - even through a week of swim lessons this month - to put his head under. He doesn’t like being splashed too much and is iffy about going down the kiddy waterslide, because you tend to get dunked at the end of it. If he were thrown into a pool as described in the article, I suspect he would be scared half to death, traumatized, and refuse to go in the pool ever again.
I have two points to make here. First, to all of the people attesting that they, or someone they know, learned to swim this way and didn’t mind it, were not scared, and are great swimmers today: Sure, okay. Some kids probably just have the personality to handle something like this reasonably well. But you know, some kids don’t. And you really don’t know for sure which is which until you try it.
Second, no way in hell would I ever do this to my own kids. I want them to trust that I am looking out for their safety, not to suspect that at any moment I might throw them into a dangerous situation and then refuse to help them. I also suspect that I am simply not capable of standing by while my screaming child is flailing in the water and calling for help. I believe I would give anyone in my way a good elbow to the gut while racing madly to the water.
So, to sum up: No, I don’t approve.
