My supervisor here at work has 2 daughters that are into cheerleading and I've been amazed at how much it cost her to put 2 girls in cheerleading. Heck, when I was younger it was practically free! Well, not free but very inexpensive. So I feel for you. That's alot of money, however, I intend on letting my son try almost anything within reason to see what he is good at and what he loves. But then if we were not a two income family, I probably wouldn't have that choice. Not sure what your financial situation is but I would try my best to encourage her and come up with the money (easier said than done, I realize). I think this sort of thing is very good for kids (cheerleading, sports,etc). Just my .02 cents.
