She does sometimes get frustrated with that at times, but more so with girls lack of effort or even knowing what they are supposed to do in certain situations.
Generally, pink unicorns, rainbows, and skittles are the status quo for 6U and 8U. There are always a couple standouts in there. But the standouts, in my experience, also were into pink unicorns, rainbows, and skittles. Moving up too much can have emotional ramifications. Older girls expose the younger girls to stuff that is not age appropriate. I recommend leave her in rec for awhile, get her lessons with good instructors, and by 10U or 12U she'll be ready to travel.
