You can send your dancers to the school I work at! We are 6th through 12th grade arts charter. Our dancers have classes in the school day for 2 hours a day plus most are on the performance team which practices another 2 hours a day. We'll wear them out for you :-)

I actually need to work on overscheduling DS a little bit more. He has school and gymnastics 1x a week and that's it. He so far has shown no interest in anything else but at home complains that all the other kids are doing things outside of school and he doesn't get to. We may add another gym session next school year and I'll also be working to convince his school that he should be allowed to participate in Odyssey of the Mind this year. They only allow 4th and 5th graders for some reason... but that's not our state's rule just a school rule.
