That thought process alone shows GTness to me, for sure. Most 4.5yos couldn't reason things out like that.
That's the thing, I have no idea what *most* 4.5 year olds can/cannot do. I expect things like that to be typical for her age peers, given the vast range of time considered normal to acquire a variety of skills. (What I mean is that the range of time for a child to gain a particular skill can vary from months to years between children and still be in the ND range. Right? I can't think of anything specific, at the moment.) It gets me into trouble; I figure that other kids her age can do it, too. Really, I'm clueless. I've read the developmental charts. Still I find myself often clueless re: abilities of kids, in general.
I have a screwy
kidometer. On the one hand I find myself perplexed when a child acts in a typically age appropriate way, e.g. a 2 year old screaming instead of using words to convey displeasure. By the same token, when some one says, "Can you believe a 9 year old is doing Calculus?!" (Shock! Horror!) I say, "Oh sure, that makes total sense."
