Tillman is an outstanding wild-life artist, and in this book a child will delight in all kind of wondrous creatures from frogs to giraffes who are getting sleepy. “It’s time to sleep, my love,”  is the repeated refrain “droned by the drowsy bumblebee inside its hive in a tree” as well as “I’m getting very sleepy now, so moos the tired milking cow” and others. A gorgeous painting of the collection of animals in a hot air balloon reminds the reader that “Your dreams will be arriving soon. They’ll float to you in sleep’s balloon.”  The story ends with assurances of love.

The artwork in a picture book is a large part of not only the charm, but  the teaching of a book. Tillman’s art says so much that needs to be noticed. Readers will see something new each time the book is read, and children will soon “read the pictures.”
