Just a slightly off topic comment about dance. Please do not lump all dance into the same category. There are legitimate dance studios out there that have absolutely NOTHING to do with competitive dance. The competitive dance world (which my DD was part of for three years) is pretty disgusting. Many overtly sexual costumes and dances. It disturbed both DH and me, and we started looking around for a different type program. And, thankfully, we found one. Not only is she learning more about dance (real dance...not hoochie mama dance), but there is absolutely nothing age inappropriate about the costumes or moves. At her most recent performance, for example, her group did one piece from the Fiddler on the Roof (where they danced wearing longish skirts, full blouses, head scarves and aprons). It passed even the grandma test....grandma liked it! The girls in the group also loved it.
If your child wants to dance, search out a good program...in general, that means avoiding competitive dance. Why we have to take an art form and turn it into a "competition" is beyond me. The only people getting wealthy out of competition dance are those that sponsor this insanity.
