I don’t have kids, but I was one. My dad taught me the side stroke fairly young, I think I was 5 or 6 years old. Neither my dad or my mom put their head under the water, but they both love the water. My mom still swims every day. They can go under, but they don’t. The first time I put my head under the water I was 8 years old at day camp, but I already could keep myself afloat and swim.
My grandmother taught me how to breath and good swimming form once I was comfortable putting my head under. Breast stroke, including the proper kick, the crawl, and backstroke. I tried butterfly now and then, but was never good at it.
I love swimming.
My dad taught me to dive when I was 8. I still have a great dive and get compliments. Nothing fancy, just straight down, toes pointed, very little splash. I can’t do it from high up anymore.
