Ready Baby? is a child-friendly pop-up book on where babies come from. A copy of the book is found inside the Gravity Falls Library.


The book is used by Mabel in "Sock Opera." She opens the book twice on a page that emits a noise of a baby saying "Ma" but when combined says "Ma, ma." When Mabel first sees Gabe Bensen, she opens it on a page with a pop-up heart four times, saying "Bu Bump, Ba Bump." in the process.


The book is thick, wide, and light blue. The title appears in purple bubble letters with a drooling baby head in the center of the cover in a yellow cloud. Underneath the title are the words "A GUIDE TO WHERE BABIES COME FROM."
