Comments seemed to peak around 3 because that was when the gap was most obvious. Here was this baby faced child reading fluently, using a very extensive vocabulary, with encyclopedia knowledge of many things in her environment and she still thought that was normal so she just spoke her mind. Now, we do get comments, but because she is extroverted and happy go lucky and popular,she doesn't present in a way that reads super smart kid from a distance and most parents don't even talk to her anymore. She still has her impressive, shocking moments, but three was certainly the year that we heard comments on an almost daily basis. I remember her holding a squirrel toy at a store when she was three and a grandmother type bent down to ask her "what kind of squirrel is that" and she said, "an impertinent one I imagine!" (it had an impish look) and the lady gave the strangest smile.
