We are in the exact same boat in our family, and our daughter is only a level 5! For us, it is not a question of affordability, but one of convenience and time. There is a huge family commitment that comes with enabling the competitive gymnast!
I laugh when I am lurking on this site and see people worried about their DDs making "only" 35s. Then I hope that these kids are competing pre-elite in California or Texas, because I cannot see our cute, gymnastics-loving daughter ever getting a 35 -- due to lack of form, flexibility, or whatever happens to be bugging her on any particular day. She struggled to even qualify last year (31!).
Our 10-year-old DD is at a good, but small, gym in the northeast. She picks up skills quickly and is strong, but she lacks flexibility (still no left or straddle splits after four years in the gym...sigh) and the kinesthetic awareness that some girls seem to have as 5-year-olds. When she encounters skills she is not good at (currently the back extension roll in the L5 floor routine and pesky handspring vault), she avoids, rather than trying to conquer and perfect, these skills. Despite being an attention-loving ham in general, she tends to "do" her routines, rather than "perform" them. She came in last at a good number of meets last year. This year (repeat L5) is looking better, but only by a little. She is a work-a-day gymnast and will probably repeat levels for as long as she is in the sport. I'm not even sure she'll compete her way out of L5 this second year!
It is frustrating to watch, as the enabling parent! I admit to gazing longingly at the prep optional team at her gym, with its 5 hours of practice a week, its four meets per year, its emphasis on skills acquisition rather than rock-solid form, etc. However, my DD insists it's JO USAG for her, or no gym at all.
So, once I get past my own issues about her gym life, I see all the good that is coming from it. She is working out 12 hours a week, which is great for her body and her head. She has caring, competent coaches who can "see" the whole gymnast. She has had to learn time management to find a nice balance among family, school and gym (in that order!) activities. She is a great student and an encouraging, supportive teammate. If she sticks with gymnastics, there will be little time in the immediate future for malls, boys and Facebook (which my non-sporty teenaged daughter has become mired in).
Okay, and I will also cop to a certain pride that DD just kicked the butts of all the boys in her class in the yearly Presidential Physical Fitness test!
I'm with Bog and ZZ. If she is happy and motivated to continue, keep her there.
