I'm not the mom of a grade-skipped child, but fwiw, I think it is going to be really tough to predict right now, at 7, what your dd's speed will be a few years down the road, and I'm guessing that the way high school-aged kids treat your dd now (as a cute little 7 year old who then becomes a pest) is going to be different than the way high school kids will treat a slightly-older dd who is with them in a classroom setting rather than in a theater situation. My advice would be not to over-worry about that at this point in time, and not to hold her back in what she is capable of re her math or any other subjects.
There may also be other options for how to feed her the advanced academics and math in particular once she hits 7th grade - online, for instance.
Best wishes,
