Board books are good with littlies. You can get bb copies of most of the popular titles

My nearly 5 year old is obsessed with books and absolutely adores reading, but he still hammers his collection (not literally). His favourites get dragged in and out of the car, shoved in his kinder bag and have the pages bent back and spines crushed as he holds up interesting pages for me to look at. We try to get him to be gentle, but needless to say I haven't yet given him the intricate "pop up" style books I have bought for him yet.

My advice is let her trash her board books and gradually introduce "nice" books under supervision.
