Dr Seuss's Sleep Book by Dr. Seuss; 1962. Hardcover (Ch-PIC)

Catch a case of the yawns with Dr. Seuss in this classic rhyming picture book. Bedtime has never been more fun! A yawn is quite catching, you see. Like a cough.
It just takes one yawn to start other yawns off.

Dr. Seuss spins a sleep-tastic tale about a very small bug and a very big yawn that spreads and spreads. Meanwhile, the Audio-Telly-o-Tally-o Count adds up every sleeping creature from the country of Keck to the Castle of Krupp. First one, then seven, all the way to the billions and zillions, the Who’s-Asleep-Count just keeps growing and growing! This book is a perfect bedtime story that will have the most reluctant readers laughing, and the most reluctant sleepers snoring!

Ninety-nine zillion, nine trillion and two
Creatures are sleeping!
So...How about you?
