Re: Where do you get your children's books?
I used to go to our local thrift stores when they had once-a-month "bag" sales - fill a paper bag with anything you want for $3. I could fit A LOT of books into a paper bag, lol!!
I haven't been in a very long time, though, since I went so overboard when DD was little. We have a whole room that used to be nothing but bookshelves. I gave away about half our collection on Freecycle (another great place to look!) to make room for toys.
