No!!!Little girls grow up so fast anyway, why pave the path in this way??
I'd be tempted to go, videotape the "lessons," and consider whether child protection should be contacted.
How much "S" do little girls require? Shouldn't they feel good about other aspects of their identity? Every developmentalist worthy of the title believes that preteen is a time of academic success, friendships, and learning to relate.
Shame on them for marketing to little girls...
Would it be okay for men to teach a class like that? Then not for women either.
