We used this book to help our son sleep through the night over 35 years ago with great success. I put our 14 month old grandson down for his nap in his crib today using Dr Ferber’s book /method ! He was asleep after crying for only 3 minutes. It works and has been a godsend across generations!
Many thanks to Dr Ferber for this book! Give it a try! You won’t be disappointed!
