After 2 years of failed swimming lessons by "professionals" I taught my daughter to swim in a few weeks using this technique (learn one step at a time).

This technique has a name? I teach swimming lessons as part-time job and I guess I'm still getting used to it not being obvious to most teachers (of swimming or other things) how important it is to break down skills into small chunks. Just out of curiosity, what progressions did you use with your daughter? I may be able to use them in my classes.
