Carl-Johan Forssen Ehrli, a Swedish behavioural psychologist and linguist has written a children’s book for the parent to read to a child. The book is designed to put the child to sleep quickly. When the parent reads the book to their child, even the most troublesome child goes to sleep very quickly. A child that would normally take 2-3 hours to go to sleep, the same child went to sleep in 12 minutes.
The book has been topping Amazon’s bestseller chart and the book is available here
