PLB 0-517-80012-8 Rockwell (who illustrated Anne Rockwell’s Halloween Day, 1997, etc.) focuses on a young boy as he and his family prepare for the birth of his baby sister. The precocious narrator confidently discusses the growth of the baby in his mommy’s womb and describes visits to the obstetrician to hear the baby’s heartbeat. Also covered are the arrangements for the boy’s care while his mother is in labor, the hospital visit, and baby’s arrival at home. The young narrator reflects on how his baby sister is not yet used to the concept of day and night and when she, at one point, becomes inconsolable, he fetches a favorite toy to soothe her. In a refreshing departure from other books about siblings, this one does not address negative feelings of anxiety, trepidation, or jealousy. Instead, the approach of the text is optimistic, reflected in Rockwell’s bright, cheerful illustrations. Age-appropriate pictures cover fetal development, including a wonderfully informative spread entitled “How a baby grows,” charting the period from conception to term. An upbeat, encouraging account.
