Winter is on its way. For Mama Bear and Small Bear, that means it's time to tuck into their den for a long sleep. But Mouse is scurrying by, and Chipmunk is still gathering nuts beside the lake. And look at Hare and Skunk, still romping through the leaves! Why can't Small Bear stay up, too? To each question, Mama Bear responds with the coziest of answers, finally painting a dreamy picture of the brightening colors and new adventures that will greet Small Bear in the spring. But first comes sleep, in this irresistible invitation to drowsy little cubs everywhere.
