Ya know, I'm still quite amazed at how a simple little question illicited 3 pages of responses.
Since I'm the original poster... the mind set was... my dd has shown some interest in some world culture/history lately, and I was looking for something to help expose her to that. If she shows an interest in something, I like to expose her to it, to see if she has any interest there she wants to explore. (kinda like art... no interest, no interest, coloring is boring mommy, no interest, and then WHAM!!!! can't keep her from drawing if I tried... the key was just to insure she had the supplies available and seeing if she had any interest) I'd heard of SOTW, and never have seen it, so was trying to see if the book would be a fit or not. Doesn't sound like it.
We've had a hard time finding books for her lately, b/c she wants a long story, but pictures peak her imagination. We've found a few books, but it's definitely harder, b/c she is almost between phases.
As for question that came up for finding a balance, but not pushing... I leave a variety of books out. DD loves her disney books and regularly brings me those, but will also bring magic school bus, magic tree house... she has brought me 100+ page books of Little Women or Peter Pan. It's pretty obvious if the book is keeping her interest or not... she won't let me stop reading if she is enjoying it.... so long peter pan book, I had to read. Little women, we stopped on chapter six. Magic school house, I have to read the whole thing.
With my oldest, if she doesn't want to do something, she generally tells us, or makes it obvious.
