My older dd is one of 5 or 6 girls in her training group that are all 11 and training Level 9 together. It is fun for the most part because they are all the same age and same interests, and in the same place in their lives. Having said that, it is also a bit competitive. I think generally speaking the peer pressure and competitiveness is positive, along the lines of we all can do this! But if one seems to have a problem with something, it is hard. They generally have different strengths, so it isn't always the same person struggling which is good. What do you think about that kind of daily competition? The first to get this skill, the last to get this skill, etc. And then what do you think it will mean at meets when they are all the same level, same age...
