Lots of stories here. My kids club's coaches are lovely. Really caring and funny and we could watch every minute of their training. There is a viewing gallery at the gym and many parents would stay and watch.
However, it was either 1 hour rec classes which were quite basic or they were plunged into this extreme training world- 4 hours (fine and what my kids would have preferred) , to 8 hours then 4 hours a day 3x a week and 6 hours on Saturday (or something like that, I can't remember). My youngest daughter quit when she was the only girl put up from a few hours to a lot of hours and she would be in physical pain obviously because she hadn't had a chance to recover. I asked her coach if she could say do half the time on saturday and work her way up and her coach refused saying that my daughter should tell her if she was in pain.
Kids aren't going to speak up in a session unless they're very confident.
So in quick succession, my 3 talented kids who really enjoyed gymnastics, quit.
My 2 eldest kids also did competitive swimming. Again, they loved it and were really good. As they moved up the lanes, they had all the fun taken out of it and it was just about getting faster to win competitions. No more fun bits of it.
Some of their friends who carried on spent a few years swimming before school and it became their and their parents lives until they too, quit.
Now, my kids only do badminton at a local club. Once a week and they love it. There are some friendly matches and some of the players do play at county level (mine did for a few years). The man who runs it is great. It is fun, sociable, a great sport and the primary aim is for kids to enjoy themselves whilst doing a sport.
Like other people have said, most will not (and do not want) to make a career out of the sport or discipline, they just want to enjoy doing it as a hobby. So why are so many clubs so intent on pushing kids so hard so that they end up quitting?
Saying that, I think gymnastics is brilliant and as long as your child is enjoying it, let her continue but be wary and maybe look at other sports. Gymnastics really helps other sports.
