Do it Again

Today was my son's second day of swimming lessons. C couldn't comprehend why he had to lie on his stomach at the water's edge and practice kicking again, because they did that same move last week.
I don't understand it; repetition is a four-year-old's raison d'etre. He who asks me the same questions over and over, wants the same books read and reread, and can watch The Big Space Shuttle every day for two weeks straight can't abide having to furiously kick his feet twice in a seven-day period?
