It's good that you're thinking about what she wants, and whether she's having fun. Over the past few years I've been watching the musical chairs parents play with their kids, bouncing them from one team to another always looking for...what? I don't know. No team and no coach is going to be perfect. Do these kids really want to have to bond with a new group every year or even twice a year?
Made this mistake with my older DS in another sport once. Don't want to make the same mistake again. He was athletically ready for much more challenge but social/mature not there.
