Have you thought of just telling her that she is going to "take a break" for a few months? I did this with my youngest. She *liked* gym, but didn't LOVE it like her sister. Frankly, she really just loved her sister and she loved just seeing her when she was at gym. Big sister would pass her in between rotations and would give lil sister a hug, that sort of thing (they are just really close!). But little sis didn't really like gym enough to work at it. So we told her that she was going to take a break, try some new things and if she missed it and wanted to go back after two months - she could do it. Her coaches were good with this- they knew all of the above and while they were fine with her staying, I think they wanted her to find her own passion too! In around three weeks, she told us that she had NO desire to go back. When we would go in to pick up her sister, her old coaches always came over for hugs (still do!) and would ask her if she wanted to come back, but she had found a new *real* love- tennis. Now she is super happy, and loves to tell her old coaches all about what she is doing. And they tell her how they can't wait to watch her in Wimbledon! (lol! Its like the Olympics for tennis!) I really don't think that she would have ever told us or admitted to us that she didn't want to do gym- that is not her personality. Taking a break really was the BEST thing for her. Just something to think about.
