Little ones play a dressed-up version of peek-a-boo in Marion Dane Bauer's board book Toes, Ears, & Nose!, illus. by Karen Katz. ""Inside my mittens I've got,"" Bauer begins. Readers lift decorative pink mittens to find ""fingers."" Snow boots, earmuffs and a scarf hide other body parts; vibrant colors and patterns add pizzazz.
