Rose gymnastics

Here's Rose at the end of the Winter Gymnastics session

Ever since Rose was 2 years old in gymnastics the coaches have mentioned that she is super strong.  I asked her coach if there was a level that would be a bit harder for next year.  Right away she said she was ready for a challenge and mentioned I could bring her to tryouts for a pre-competitive level.  So I figured why not, and I took her to the tryouts.  Now they have placed her in the highest level for her age.  Even then she would be the youngest in the class.  They want her to train for 4 hours a week.  It starts in July and goes all the way until next june...49 weeks straight.   We aren't sure what to do about it, as she will also have school next year...plus she's 4.  At the same sense, it's exercise, and if she is talented, then maybe we should encourage it.  What to do, what to do.  The funny thing is that we always talked about Rose's dancing and forgot about gymnastics.  Meanwhile, she's a born gymnast. Also will probably have more of a gymnasts stature. The funny thing is that at her age she fully doesn't comprehend being skilled at something. I have some more questions to ask the club, but we also have the option to send her for 2 hours a week.  With the 4 hour thing comes a lot of parent volunteer work as it is part of the competitive track and the rates for the classes are lower than the recreational. Not sure what to do. I would have thought it was ridiculous, but faced with someone telling you your kid is talented, it's hard to know what to do.  Plus I am around to get her there and back, not an option everyone has.
