Full of wonderful yawning creatures who spread sleep thoughts at bedtime, this book is the perfect remedy for children who don't want to go to sleep. This delightful book forms part of the second stage in HarperCollins' major Dr. Seuss rebrand programme. With the relaunch of 10 more titles in August 2003, such all-time favourites as How the Grinch Stole Christmas!, Mr. Brown Can Moo! Can You? and Dr. Seuss' Sleep Book boast bright new covers that incorporate much needed guidance on reading levels: Blue Back Books are for parents to share with young children, Green Back Books are for budding readers to tackle on their own, and Yellow Back Books are for older, more fluent readers to enjoy.

Dr. Seuss' Sleep Book belongs to the Yellow Back Book range.
