Hmm. Ok, so maybe we should be expecting something vaguely like 3ish for the chapter books thing... Or maybe not

Newmom21c: sounds like yours and mine are on the sameish page, anyway! DS has been particularly interested in one of my stats textbooks, which he goes 'round the house hugging & trying to get the visitors to read to him (many of them are mathematicians, so many of them are... amused... If he starts doing linear regressions by the age of x, I certainly won't be able to say I don't know where he got it from <giggle>)
Ooo. I just like thinking about books. It makes me happy. I'm such a crazy person.
