All the more reason to put her in one, IMO.
1. She's interested in it for herself.
2. Because she is so "girlie-girl" knowing how to defend herself from others who will take her "prissiness" for weakness is vital. ---We all know a "BULLY" will pick out whomever he or she feels is a weaker opponent, viewed as "prey" for the "kill." --- So, IMO, it's important that you teach her that, in spite of all her "DIVA-NESS," she better be prepared to "get down and dirty" if somebody puts their hands on her.
