Has anyone's DD had competition with another sibiling in gymnastics? Or cousin, friend? My girls are both on level 5 and HATE it when 1 starts a new skill or gets it faster then the other. Yesterday, Leah started working on backtuck drills and Lexi came home crying because she wanted to do them too. Or when can hold a handstand longer (usually Lexi) Leah will pick a fight with her or ignore her. Please help!
