When my oldest was 3, I signed him up for the creative movement classes at our local dance studio in Fairfield County that many of the kids from his preschool also attended. As he got older, he continued to love dance class--he didn't (and we parents didn't) have any Baryshnikov delusions--but he was always happy to boogie. Every year there were fewer and fewer boys in class and though he was always welcome in every class, he started to feel more and more self-conscious until finally he decided to quit.
He got busy with other things, and I let it go as just one more thing he had grown out of, but one weekend after a particularly intense round of Just Dance on the Wii (which I totally owned, by the way), I asked if he wanted to find another dance class. The search was on.
(Note: Generally boys are welcome in dance classes at all studios even if the class description does not specifically mention boys; however, for the purposes of this post, we are focusing on classes with particular features or pricing for boys.)
