I think the hardest part of having an advanced little one is the lack of peer interaction. Both my children have had a hard time when they were little figuring out how to socialize. I wish that there was a way to do some kind of identification and get the little ones together. I wonder when I am older and the kids grown about starting pre-school weekends or camps and kids from all over could meet each other. (I doubt I will care by then, and I am way to busy now....so its just thoughts) My DD14 has struggled with finding peers all the way through. She attended CTY this summer and felt what it meant to have friends for the first time. Hence she is depressed now...but anyways I think the little ones do need a CTY or Davidson. I think for myself it is the isolation that kind of pushes one to want to obtain testing...somehow a way to reach out and connect. Good Luck.
