I don’t want him to lose this love. I don’t want him to question whether he should be doing this. For one thing, he is damn good at it. For another, he enjoys it. I want both my kids to feel comfortable and self-confident. I want them to feel "safe" doing whatever it is that makes them happy.
Just for fun, I like to show him cool actors and famous people (boys) who can dance. This is one of his favorites. And mine, too. Silly? Yes. Scrubs is a comedy. But that guy has had some serious training.
Incidentally, this video has helped my 9-year-old soccer, basketball, baseball, football fan to think dancing is cool.
