DD is 7 and L4. She was singled out to move up this past year to uptraining with L6/7 girls. Our gym is very small so no L5. The group thinned out over the year to only 3 girls and now is being merged in with a larger group training L7-10. DD is fine with skills and improving rapidly (far beyond old teammates) but very up and down emotionally. Stuck between wanting the challenge and missing the team atmosphere where you are all working on similar skills and routines and similar age. She can go on either team- the advanced or L4 where she likes the girls but would be less challenged. As a parent, her happiness is my main concern and if she is unhappy I think she will eventually want to quit which seems sad as I believe she loves the sport. Any guidance?
