Library Books

I checked out a few books from the library and he absolutely loves some of the books, 2 in particular.  Well, I'm not sure if he likes these books, or he just likes being read to (my wife suggested the latter).

I'm thinking about going out and buying these books, but I'm not sure how long they will hold his interest.

Also, I can't help but wonder, if I go and just check out new library books, if it's better for him to get new stories.

I do recall that my younger sister, when she was a baby, she liked watching the same movie over and over again.  Almost think that there is something about repetition and familiarity that infants and small children enjoy. There was a period of time where she would keep watching Disney's Aladdin over and over again, until everyone in the house could quote the movie verbatim, and just wanted to cry.
