Adults have a long history of trying to find morals and lessons in children’s literature. But what happens when a seemingly innocent book about a boy and a hungry mouse becomes fodder for the culture wars? Over the last decade, Laura Joffe Numeroff’s If You Give a Mouse a Cookie has been adopted by some on the right as a cautionary tale about government welfare. In this episode, we explore the origins of If You Give a Mouse a Cookie, the history of adults extracting unintended meaning from children’s books, and try to figure out how this particular kid’s book became a Republican battle cry.
