I remember having the same question when my girl was new to team gymnastics. Given your question specifically "What you wish you knew at this
level?" I'll have to say:
First, I agree with gymgal:
I wish I would have known not to be so narrow focused in the early stages. When she was going only 2-3 times a week, I was very concerned about her missing practice, even for family things like vacations, relatives visiting, etc.
Don't focus too much on gym right now or for quite a while even. She needs the diversity of activities both mentally and physically. Several of the early injuries my kiddo has had were due to overuse and use in only specific ways (eg: there's far more forward and backward motion, less random or side to side motion, which affects ankle strength laterally, knees, etc..). I wish I'd kept her doing other sports too for as long as possible. Also, now that my girl is older, I regret not taking the time to travel to see family and take vacations. Kids need to know that these things are things they do
, not who they are
. So encourage your girl to do a variety of things and enjoy friendships/activities outside of gym too. Keep her doing chores and part of the family's activities as much as possible. They need those things.
Secondly, I'd say take everything with a grain of salt. I was once told by a gym owner, in summation, that you just can't predict any of it. A girl who is talented at the lower levels, might not be able to be as successful at higher levels. Or they may struggle in compulsory but be very successful later.. like the struggle of the lower levels brought out a strong work ethic and perseverance that made the difference. They may decide they are 'done' at age 8, 12, or 17. Take it all one day at a time and know that she (and you) will grow and change in so many ways in the next 13 years - with or without gymnastics. Remember to keep your focus where it needs to be. Your focus is on your/her relationships within your family, and her health/education and mental/emotional/etc.. development. The gymnastics part is up to her and the coaches.
And lastly - and most importantly to me - have fun with it. It can be hard not to get excited and want them to do well, but the desire has to come from them. The skills will come. Success and struggle will come. Great adventure and fun will come. Injury and growth and sore muscles and conflict and fear and triumph will come. All of it. Teach her, by example, to ride the waves and see it all as part of the experience and as opportunities to grow and learn.
