Since she isn't born yet I suggest that you start with some touch and feel board books! My son LOVED those.
He had a fun one that is in pretty bad shape from constant loves. It was all about dogs. You could feel all sorts of different types of "fur" He loved it.
And at about 18 months his favorite book was my BIG book of animals. I believe is what it was called. Had all the farm animals in it and all of the regular pets and such. He loved to point to each animal and find out what they were and what sound they made. Over and over and over again :)
And then when he was like 2.5 we found the little book of animals or something. It was full of wildlife. Jungle animals, Arctic animals, sea life, birds and so on. He loved to go through and tell me what all of the animals were. Again over and over again! He is almost 5 and still loves these two books! They are also the hard board books so good for little ones :)
