In nearly every pregnancy-related blockbuster, the audience sees a quick slip of What to Expect When You're Expecting or The Expectant Father. In Knocked Up, Seth Rogen's character buys a stack of pregnancy books and swears he will read them before the birth of his child. On a pregnancy high, many women with child run to their local bookstore or library and take on as much reading material as possible. Whatever she doesn't buy, a friend is sure to send to her.

Pete Wentz told People:

I'm reading a lot of books . . . The biggest one is The Expectant Father. It's a really good one.

Did you read up on pregnancy books when you were with child?
