My CP is in a gym where every coach is credentialed and they are all about perfection over progression. We came from a gym that did not have any coached credentialed, and where skills were pushed. My 5/6 year old at the time was working on a bhs when we came to new gym. We have spent the year correcting bad form. She will move to a mini 1 next year, so they are in no rush to teach her a bhs. At first it was so weird to me and I didn't like the slower pace. But seeing how gorgeous her tumbling is now, and the fact she has all of her level 1 skills solid (including opposite side, switch leg, etc), I really appreciate the way this gym does things. I also appreciate the fact they are all credentialed and are all about safety. This gym is quite a bit larger than our previous gym, but I don't see nearly as many injuries.
