I made a similar statement a year or so ago on this board lamenting we hadn't started earlier. Well, each kid is different, but mine didn't start Rec until 6 3/4 and only started a 1x week preteam1 after she turned 7. I knew nothing about gymnastics when I brought her in for that first rec class. It never occurred to me that it could lead to any kind of team. Though strong and lean as a cheetah, her form/dancy-ness was terrible (stiff) and she was as flexible as a marble pillar (lol), and also ridiculously tall for her age. I really never ever ever imagined that 'her sport' would be gymnastics(!).
Well, now she is 8.5, and getting ready to compete in JO level 3 (nearly skipped it for level 4), and is at the top of her group in skills, and holds her own now on form and dance elements. Somehow things came together for her, as she is an incredibly focused, hard worker. True, if I had started her even earlier, she might be ahead a level, but she has caught up with most everyone who had that early advantage. I have seen some other 'later starters' do the same.
So you never know! Just sharing to show all is not lost, and her success really depends on her own talent and drive. Hope she continues to love gymnastics!
