Haha, thanks momtofour (and everyone else) for your responses.
@Cricket DD began talking around 9 months. She actually started signing around the same time and the signing took off faster than the words. We had to make a list for the daycare teacher because she didn't know what DD was trying to say.

Anywoo, I think at this point, we'll just wait it out and see what we think in a few years. If we still feel like this is a gifted child, then we will re-test. If not, we will just enjoy our high achiever but not gifted DD.
