Wow. This kid has both incredible strength and flexibility... and she can tumble.
If she has the right coaching and supportive parents and can stay healthy... I know it is a lot of what ifs... but I beliieve she can go as far as she wants to.
I've seen a few gymnasts that have this type of strength and flexibility.. and quite a few of them have gotten burned out. Their parents were very pushy though. So.. As long as she loves it and is the one asking her parents to take her to practice than that should never be a problem.
But yes the kid has a lot of talent. I'd run with it.
She does display a lot of strength and flexibility. Seeing that she is a level 5 and she is on a team, the gym she trains at should definitely get her involved with TOPS. At her age and with her already displayed strength, she would do very well.
The only thing I will say is that she is very loose. I know that she is just fooling around and having a good time and that could be why she is like she is, but she would excel if she could tighten up her body and point her toes.
Good luck with your dd and remember that gymnastics is a marathon, not a sprint. Don't push her too fast or too hard, let her set the pace.
