Nerdnproud - I agree with the lonliness thing...no one to talk to about things and I have found it hard to find other families since we live in a very small, rural town. I have figured out from talking to our daughter that we have a total of 3 (one being my DD8) gifted kids in our elementary school (K-5). The other 2 happen to be boys.
I also like what you said about worrying that my child wasn't really gifted for whatever reason. DH and I tossed this back and forth many times wondering if we were just imagining how bright she is or that maybe she isn't that different from every other child. Glad to know we aren't the only ones!
