She's already had a successful level 2 competition season, right? I agree it's worrying that the coaches allowed her to run off to another group, but I honestly think that has more to do with being unhappy at being demoted (which she absolutely was) and being bored than indicating that she is now incapable of team level training. It's one thing to hold off on putting a kid in team because of maturity issues, but it's a completely different thing to have a team level gymnast, with a competition season under her belt, suddenly practicing a quarter of the hours with significantly less advanced students. It's a recipe for boredom and frustration. I also have experience working with kids and if a kid is already prone to focus issues then guaranteeing she's going to be bored is the worst possible course of action. I'm sorry, there are teams that successfully integrate four year olds into practices. A good coach is able to handle kids of different ages and maturity levels and work with the parent on some of the strategies others have discussed (sticker charts, for example) to get the gymnast where she needs to be. I'm baffled that, after reading your description, some are telling you to put her back in rec. Find a gym that's able and willing to work with her in a class that's appropriate to her (can help her with focus while still being developmentally high enough gymnastics wise) and yes, help her in any way you can outside of the gym. But don't stick her with a group learning to cartwheel and expect her to magically want to pay attention to that.
