In the FWIW department...
I think early milestones tend to indicate (though do not guarantee) GTness, especially if a child reaches milestones early across the board or at least in most of the areas not tied tightly to motor skills.
Later milestones, however, do NOT mean a child isn't GT. That's very important! There are just WAAAAAAAAAY too many cases of kids who didn't speak until 3 or 4 or whatever, and then spoke novels, or the kid who didn't read until 1st grade, but was reading at the 8th grade level by the end of that same year. I have a deep mistrust of anything that is used to "rule out" kids, especially kids who are pre-K-aged or so. There's too much going on there that we can't necessarily see.
I, too, would suspect GTness in your child, HoosierMommy, and I'm with Lorel that it seems too early to tell level.
So there's certainly no reason to think you're crazy, no matter what your family seems to think!
