DD has been with a USAG for only a year. I found the ChalkBucket when deciding if a ten-year-old could join USAG. Most individuals on this board offer extremely accurate information on gymnastics. They use stories of their own experiences, or their child's experiences or experience garnered through coaching to help others find their way. At the beginning of this USAG journey, I was hesitant to listen. I never thought I knew better but I questioned what I was learning from all these great folks. Turns out most everything offered here is accurate.
I apply this to this post in this way. My DD skipped levels 1-3 competed once at 4 once at 5 and skipped 6. She competed her one and only season of USAG at level 7, she is currently training level 8. She had a successful season and enjoyed that journey. What I learned during this first year is this: Every child is an individual, every child has their own motivating factors, and every child has a dream ending to their own gymnastics journey. It is their journey and as I have learned from many great folks here as a gymnastics parent my jobs on this journey are to pay the bills, provide the transportation, and support my child by being her soft landing spot when things get hard and scary because as the levels increase gymnastics will get hard and scary.
Ask your Daughter what motivates her to do gymnastics, is it skill acquisition or is it competing? Help her make her decision based on what she uses for motivation. In the end, the coaches who offer your their thoughts and plans for your child, for the most part, know what they are doing. Find a coach that fit your family then trust the process.
