Colorful, if pedestrian, picture-book treatment of the arrival of a new baby sister. Janine, a three-year-old black child, is shown going about her daily activities just prior to and shortly after the birth of her sister. The watercolor illustrations are bright and busy--Janine at home; at the playcenter; at the hospital. While there are several Briticisms in the text, they are easily understandable in the context. This picture book also displays all the ""right"" elements--a bright little girl, an attractive variety of ethnic playmates, and the successful resolution of possible jealousy by an understanding mother--but in a didactic if functional manner. Everett Anderson's Nine Month Long (Clifton), Peter's Chair (Keats), or A Baby Sister for Frances (Hoban) have more child appeal and are more successful, as they have both story and message.
