Hello! I am a new CB member, though I have been reading on the forums for a few months now. I have 6 yo and 8 yo DDs who have been doing gymnastics since fall of 2012. At the girls' gym, they give out invitations for new levels at this time of year, and then girls start in their new levels in June. 6 yo DD has been in a Hot Shots class for almost a year, and has now been asked to start preteam class. 8 yo DD has been in preteam class for a year, and has now been asked to start on Level 3 team. They are both very happy. However, my DH has expressed that while he has been fine with Rec level gymnastics for overall fitness and activity, he is hesitant to let either girl go beyond preteam (7 hours a week) as his perception is that higher levels of hours spent training gymnastics will impair growth/normal physical development, and will be bad for their growing bodies all around. My perception is that gymnastics has made my girls strong, fit and confident, which I love. The gym emphasizes safety, I feel confident in the coaches, and I really like their overall culture/philosophy. DD8 will be crushed if she is not allowed to do team, and will not want to be in preteam class again with her little sister (this would be her only choice if she does not move to team). I would like to try to present DH with some information to address his concerns. I am going to do my own research, but thought I would ask the experts here to chime in and perhaps point me in the right direction. Thanks in advance for any help you all can provide.
