Lock 'Em Up: The Stories Behind 12 Banned Kids' Books

A whimsical story about a little boy named Mikey who goes on nighttime adventures to the Milky Way, In the Night Kitchen is controversial because of little Mickey's choice of attire for much of the story: none. The little boy spends a decent amount of time sans pajamas, and the illustration of the young child's private parts has consistently earned this book a spot on "most frequently challenged books" lists since its publication in 1970.
