I bought her a set of Speedo swimming equipment. She tried to swim before and told me about coaching, and then I said it was not as good as I taught her. After all, I have learned swimming for two years. Fumbled for many methods.
Sure enough, I was born to be a teacher. She was very clever and learned almost all of it quickly. I taught her to break up the three parts of swimming, learn to breathe first, then learn the feet, then learn the hands, and then connect them together. Basically it will be done a few times.
