You have to be careful too, our DD is 10 and is training for hopes this year, this is a very regimented program and if you are not careful burnout can be very high. You are talking about 20-30 hours (closer to 30-35) at this level of training you are talking about a very big potential for injury. You have to weigh your options and understand what you are getting not only your DD into but your family. Gymnastics is a wonderful sport and can do wonders for children but elite gymnastics has become about harder and harder skills. The attitude is that they sky is the limit.
When you have a young child on an "elite track" there is a serious balancing game to play to make sure that the child is healthy and happy. Happiness comes first in my mind, and although no one likes to admit it as gym mom's we do get over involved and sometimes forget that this is our childs sport, not ours. If your child wants to go elite and she knows what that means then go for it. Just make sure she really knows what it means - not just the end result. Coaches are going to push kids they see talent in and sometimes unintentionally they push them before their little phyche's can handle that much pressure so again, I caution you about moving up that fast.
I think about it in these terms... Right now my DD is 10, she's training for USAG level 9 and also hopes. If she continues to train for elite she will be 11 at level 10, 12-13 as an junior elite and still have to wait 5 years to go to college. That's five years she has to train 30-35 hours a week and beat the heck out of her body.
With all that being said, I don't think it's necessarily bad for kids to go elite. I just think people need to go in with ALL of the information not just the thought of how wonderful it will be to have an elite gymnast because the truth is there are very few elite gymnasts for a reason.
