Listening one's self to sleep is a technique that does not have to be pointed out to small children. They are at it before they can talk, or even be read to. The sounds they are likely to hear depend a lot on where they are spending the night. Now, this slight effort features the sound of breezes, rustling leaves, swallows, katydids and frogs. These sounds are spelled out and repeated for a chanting effect that could prove to be darned embarrassing for the more inhibited reader-aloud. The rhyme and rhythm are not enough to keep anybody awake-- but they are old enough to keep the alert from going to sleep. The illustrations by Beni Montressor are admirable-- they go from bright yellow day to dusk to nightfall-- but they will be more appreciated by adults with an eye for artistic technique than by children.
