The potty library

I just bought a crap load of potty books. We're not officially ready to say we are potty learning but we've been talking a lot about the potty lately. TG currently has two potty books but I figure the more the merrier. I figure if I'm going to be in the bathroom for an extended period of time with TG, I might as well have an arsenal of books to read while there. I usually buy my books used as I feel that it's a good way to lower my carbon footprint but something about potty books compels me to buy new books.
