Query: It's a hit!

I bought this book for my 18-month-old eight months ago, and it's been a favorite since day one. It's small enough to slip into a diaper bag or purse, and she never tires of lifting those flaps and saying the animal noises over and over and over... It's showing a lot of wear (love) and we'll probably have to replace it soon, but it's so inexpensive, who cares?
