My nine-year-old son has had happy feet practically since birth. He already has many years of tap-dancing under his belt and he took ballroom dancing in his school last semester. He was thrilled to be dancing (in school, no less!) and quickly picked up the foxtrot, merengue, swing dancing and even the tango. The ballroom dancing program hadn't even wrapped before he was asking if he could continue to take lessons outside of school.
I said, of course... but then I started doing the research. To my surprise, while there are plenty of schools that offer one-off classes here and there like flamenco or salsa, and lots of ballroom dancing studios for adults, there aren't that many programs for children that focus solely on the genre. However, I did find a handful of NYC spots that can give your little movers and shakers a dedicated ballroom dance experience, plus info on how you can bring ballroom dancing to your kids' school.
