Good Night, Feet

``Good night, feet. / You've worked hard today. / I need you, feet, to run and play,'' begins the hushed, rhyming text of this soothing bedtime read-aloud. On successive spreads of Morgenstern's first book, different children bid goodnight to other parts of the body as well--head, hands, mouth, ears and eyes. In her stylized, at times dreamlike pictures, Smith uses a palette of unusually luminescent colors. Subtle variations distinguish each scene: the beds span a range of styles and windows open onto a desert, farm, ocean or garden scene. At the book's close, a mother pulls down the window shades next to her drowsy daughter as the verse advises the eyes ``to start to pull your shades down too.'' By this time, the eyes of sleepy listeners are likely to be closing--most contentedly. Ages 2-6. (Mar.)
