I highly recommend, if she wants to switch, that you start as soon as possible. Two stories: One is my girl. We knew she was hurting but didn't know that it was "important". She didn't complain much, just said it hurt sometimes (she was trying to hide it so that she could keep competing). She was accepted to her new gym and, the same day or the day before, got diagnoses of injuries that meant conditioning and trampoline only. She spent over 2 months pretty much just conditioning and practicing twists at the new gym. I know it was frustrating to everyone and not ideal, but it gave her a chance to watch the practices and learn the culture of the gym before she fully joined in. If your girl is going to be on the injured list, she could at least be benefiting in that way. Additionally, she could start training bars with them sooner! They'll want to change things.. what a great time to get started on that! Maybe even work bars upgrades. Second story: We had a friend who decided to wait until the injury resolved.. by the time it did (and a reinjury before they could switch and more time off), the environment of that old gym had worn her down. It's not fun to be injured, and to be 1) injured knowing that you're not sticking around and 2) what you are doing is not really taking you closer to your goal? That's hard. I really believe that if friend had switched sooner, she would have continued rather than quitting to move to a different sport. Granted, that's an extreme example.. but think about your girl's mindset. If she wants to go, start talking to gyms. I guarantee it's not the first time they've had this situation. With videos, scores, bars, and just watching how she interacts with the coaches/girls etc.. how she acts when injured? I'd think that would be a great indicator to a coaching team of what your girl is really like.
