We've been doing a lot of Berenstain Bears and Clifford (pretty much exhausted what our libraries have of them), Thomas the train books, the little soft cover Disney princess, Cars, etc. books. DD also likes books with Sesame characters, and I've read her the "If you give a moose a muffin"-type books. We also tried one Arthur book.
What else would you suggest? DD isn't super girly, but also isn't into books about pirates, trucks, etc. I'd like to start requesting books through the library, since it takes too long to browse through the stacks and pick things.
Thanks for your help!
