Wave Goodbye

""Wave your elbows, wave your toes./ Wave your tongue, and wave your nose."" Not just for hands anymore, waving is a way to get the whole body moving in this cheerful if slight volume. Rather than waving hello on arriving at a birthday party, a group of children ""wave"" their knees, in a high-stepping, high-spirited gesture, while others wave their ears (using fingers), wave their hair (girls swing their braids and ponytails), wave their bellies and derrieres, in a rollicking birthday dance. Newcomer Williams uses watercolor, pastel, pencil and gouache to create warm but otherwise workmanlike scenes of racially diverse, rosy-cheeked revelers. Reid's simple, sing-song verse, on the other hand, will tempt kids to jump up and join right in. Ages 1-5. (Mar.)
