Look at the positives.
It's social
Interaction with both peers and adults
It requires co-ordination; memory; timing; fitness; strength all of which will improve as she does it.

I feel some shame in fanning the flames of paranoia, but with all the shit that's come out over the years about what happens to children in churches, Hollywood, gymnastics teams, [i]etc[/i]., I don't think I'd let my hypothetical-daughter within a hundred miles of a closed off environment under the control of a fellow-responsible-adult.

I don't know anything about cheer leading, but I used to teach guitar and the absolute worst was when I had a student who was being forced by his/her parents to be there.

If your daughter has an activity that she genuinely loves doing you should let her do it because other wise she might be sitting on the couch with her iPad

Cheerleader isn't a career

Yeah my daughter did 2 hour twirling classes at ages 6,7,8,9, then she quit for another sport
She was happy to go and enjoyed it

When you get negtive reports from school take an interest. Shes keeping fit n healthy, much better than 2hrs of mario cart!

she has plenty of time to worry about careers later. for now its just a hobby/activity. let her have fun.

Is it a competition team?
