When we skipped DD8 into fourth grade in our area with a high amount of redshirting, we told her not to mention her age. She's a fourth grader, and that's all anyone needs to know. That way, they won't treat her any differently. In every other way, she belongs with 9-10yos, and you wouldn't be able to pick her out of a crowd of them if you didn't know her. She's one you could call "globally gifted," because she's ahead of the curve in every domain... physical, emotional, and social as well as the intellectual.
If DW's history is anything to go by, DD will hit menses next year, so she'll be early on that, too. I'm hoping that won't be the case, because it could be a harbinger of female health issues DW also experienced.
