There are so many great kids books out there! I would definitely stick with board books for now, and most books have a board book version. We love Eric Carle (Very Hungry Caterpillar, Papa Please Get the Moon for Me), Patricia Boynton (The Going to Bed Book,etc), Clifford the Big Red Dog, Curious George. The Olivia books are adorable. My 2 year old loves lift-the-flap books. He loves pop-ups too, but you have to supervise closely. Touch and feel books are also great. Books of songs are great too, we have a couple of Raffi ones (Wheels on the Bus). We love to go to Barnes and Nobel, they have a train set in the kids' section,and you can browse the books and get some ideas. Also, check your library, they should have board books you can check out.
One other thing, my 2 year old loves to read the same books over and over. So while you may be bored with your books, your daughter is probably not! I've even gone so far as hiding the books after reading them about 14 times in one week! Have fun!
