“Just throw the kid in” This works for just about everything, you’ll be surprised.
Dinner? Just gather the ingredients ( to be fair, they’re still kids ) and throw the kid in. They’ll be a master chef in no time, it’s natural.
But seriously, i also learned by instinct, but i remember lots of kids were cautious of and some were really afraid of water and needed a little teaching and patience. It was part of school here in Germany, no opt-out.
