Book Promises To Put Kids To Sleep In 7 Minutes

PHILADELPHIA (CBS) -- It may sound too good to be true, a book that promises to put children to sleep in just seven minutes.

The book is titled The Rabbit Who Wants To Fall Asleep. It is written by Swedish psychologist Carl Johann Forseen Ehrlin and it is at the top of Amazon's best seller list.

In the book, "Roger the Rabbit" employs psychological techniques like frequent yawning to get kids to sleep.

A California family decided to try it out.

Mom, Tara Schuler, says, "This book promised one read-through then lights out, that's pretty tempting."

"The pace of the book and the way they have you read the words, it's all about emphasizing falling asleep."

It took the family more like twenty minutes to put their three-year-old to sleep.
