Lazy Little Loafers by Susan Orlean

The book starts out with the question, "Why don't babies work?" and the rest of the story follows the investigation of the main character, a savvy New York little girl, who figures out how it is babies are able to pull off such a life of leisure.

It's a great book with a unique perspective on babies with a good bit of humor too.
