Book excerpt: Imagine have four beloved teddy bears, each of whom is afraid of something at bedtime. That is the challenge for the little boy in Jim Aylesworth's charming bedtime story, Teddy Bear Tears. Just as the boy is ready to settle in for the night, each bear -- Willie Bear, then Fuzzy, Ringo, and Little Sam -- begins to sniffle and each's particular fear has to be explained away. Whether it is noises outside or concern that there might be something scary under the bed, our hero offers explanations for each and, in the process, just might make the nighttime worry-free for himself, too.
