For most authors the goal of their books are to immerse a reader into a story, making it hard to put down. But the latest publishing phenomenon which is topping the Amazon charts  promises to do the opposite, it is a book to put children to sleep in minutes

“After massive feedback from parents all over the world, it’s safe to say that The Rabbit Who Wants to Fall Asleep is a quick and guaranteed way to help your child relax in the evening or during a nap,” claims its description. “No need for How-to skills, it’s as easy and simple as reading a normal bedtime story with [an] improved language pattern that will help your child to relax and fall asleep.”

The Rabbit Who Wants to Fall Asleep follows Roger the Rabbit as he and his mother set out to visit Uncle Yawn to help him doze off, meeting pals Sleepy Snail and the Heavy-Eyed Owl on the way.

The book was originally self-published in 2011, by Carl-Johan Forssén Ehrlin, a Swedish behavioural psychologist and linguist. An English translation was published in April 2014 and has since surged to the top of Amazon.co.uk’s, moving into the top spot over the weekend in both the US and the UK.

The 26 page paperback is the first self-published work to ever top the Amazon charts uses psychological and positive reinforcement techniques to help children relax, focus and ultimately fall asleep. Parents are instructed to yawn often, emphasize certain words and speak in a slow and calm demeanor when reading words in italic. Though the book has illustrations, children are asked to just listen rather than follow along.

“I had written books before about leadership and personal development using these techniques but I got the idea for a children’s book while I was driving on a long journey with my mother and she fell asleep and I got the idea of how I could use my methods to help children relax” he said.

“When we stopped I wrote it all down on a napkin but it took another three and a half years to come up with the perfect story so that all the techniques were used in the correct order.”

Forssen Ehrlin even played recordings of the book to his own child Leon while he was still in the womb, and now puts on the audio book to help him fall asleep.

With the book now translated into French, German, Portuguese, Spanish and Italian, English, and four more languages on the way, Ehrlin is now planning a follow-up which helps children learn how to use the potty.

“I am amazed how successful it has been,” he added. “My inbox is full of parents who say it has really helped their children to relax and fall asleep.”
