"Go the F*** to Sleep" has become a best-seller on Amazon.
Last month we told you about a children's book that's actually not for children, it's for their parents. It's called 'Go the F--- to Sleep,' and it's been a viral sensation: a PDF was leaked on the internet and its instant popularity sent it to #1 on Amazon's top seller list weeks before it went to print. It's been optioned for a movie by Fox studios and Samuel L. Jackson was hired to read the audio book. Author Adam Mansbach joins Madeleine to talk about the universality of bedtime battles.
