Some children fight sleep with all their might. And we can see why - it is so exciting to be awake! But nobody can live without sleep, which is why we've created this bedtime ABC, a book with the power to have everyone nodding off long before the alphabet ends. It never fails. Some people begin to yawn by the letter 'B'; others go out like a light at 'P'. Almost all arrive at the 'S' page already snoring. Even the title of the book fell asleep.
