I’d taken Red Cross swimming lessons for a couple of years and still couldn’t swim. My mom got the instructor to give me some “private lessons” one on one when I was about that age. Lesson #1, he basically forced me to quit messing around and got me to float, then took me into water over my head and let go. I swam! Not very well of course, but just like that the switch was thrown and my brain knew I could do this. By the next summer I was on the swimming team. Hope it goes as well for your grandsons.
I learned how to swim in ocean water, salt water is much more buoyant than sweet water. Any ocean water around? In Europe I’ve read that many swimming pool have salt instead of chlorine, good idea as chlorine is so nasty too.
Just a thought. I hardly remember not knowing how to swim, the earlier the better. As long as safe of course.
Have fun with the g’sons!
The trick is to just get yourself horizontal. After that, easy peezy lemon squeezy.
I should write a swimming book for black people.
