No question is a stupid question.
I do not show, but I enjoy learning and perfecting everything. That's what I love about dressage- there's just SO MUCH to learn, and you're never done learning! It keeps it interesting!
Right now I do not have the money to show, and I probably won't have the money or time for a few years at least. And even then, I don't know IF I'll show. Until then, I plan on riding my horses and learning as much as I can. For me, the goal is to master one small thing per day. I don't have any interest in blue ribbons or the spotlight. My feeling of satisfaction comes from executing a perfect move, or teaching the horse something new and having the horse understand. But it really depends on what type of person you are. Some people are more goal-oriented. I'm the type that just loves to enjoy the journey.
As a side note, I did know a teen whose mother just pushed and pushed to improve her riding skills so she could show. It was completely turning the teen away from horses altogether, and the trainer saw this, and took the teen under her wing. She put off the mother so that the girl could enjoy learning, although I know there was quite a bit of pressure to show, show, show still coming from the mother.
My father did the same thing with me and softball and martial arts. I was born with a good throwing arm, and good upper body strength. But everything became a competition to him, and it ceased to be fun for me.
So really, it depends on how you approach showing. You might let her dabble in it, and experience it, but I wouldn't push. (Which it doesn't sound like you're that sort of parent anyway!)
