My DD has lots of picture books, but I would like to get her some mroe factual books. we're out of the first words stage, but I'm at a loss at what is the next step. She loves nature so I would like to find her a book that is age appropriate that descibes different kinds of insects and trees etc or even something like an encylopedia type thing, again age appropriate. I don't want to stuff her full of facts but there must be something out there that is factual but aimed at toddlers?
