Caleb's swim instructor is teaching him to kick his legs more, instead of doggy paddling through the water, so she's taught him to squish his ears with his arms while he swims.
I tried to teach him to put one hand on top of the other, but he insists on doing it this way. Hah!
I was so surprised by how much his swimming improved this week. He swam longer distances and his kick was really good - better than some 3-year-olds (or so I was told by one of the instructors). And this is all because he kept reminding himself throughout last week that when he swims, he needs to squish his ears.
