While I understand your frustration, and think it is within your rights to look for a gym that has an opening that is appropriate for your child...( and that doesn't throw kids out of the gym). I think you need to keep in mind that a team's composition will largely depend on what other kids can do also. It is entirely possible that there were too many flyers, and that your daughter just didn't make the cut based on the comparison. Or showed signs of being scared, or not quite ready to fly at a higher level. If she is small, and they can't use her as anything but a flyer, then they have to choose who is best for that team. It is difficult, because you're right that she can't learn higher level flying without trying it... but it kind of sounds like she didn't show signs of being ready to try. A good coach can see potential though, so maybe having her somewhere she is more comfortable might be beneficial. Or maybe you could arrange for her to be an alternate?
