I agree with PTP. Early reading never seemed to help anyone appreciate giftedness in my children. Honestly, nothing seemed to help our encounters with teachers early on -- not test scores, not interest, not ability, not depth of understanding, not vocabulary. I found that once my children were in other environments including private instruction, clubs, online environments, courses with higher level teachers or professors, then suddenly their abilities were appreciated and celebrated.

MegMeg -- I would hope your DD's preschool teachers would appreciate her capacity, but please don't be surprised if this doesn't happen. I had one K report card that announced to me that my child could recognize letters when he'd been reading for almost 4 years by then. It's been my experience that recognition of unusual gifts says more about the person recognizing than the student being observed!
