The third book about the endearingly self-possessed Christina, who now constructs a train of boxes and string for her many toy bears (she liked them ""most after sugar on toast, and before her mother and father"") and takes it on a neighborhood excursion--while her parents bring home her new sister. It's an eventful trip--boys throw tomatoes at them, and they get a little lost--that's warmly concluded with a hug from Dad and a new bear for the baby. An affectionate look at a small but indomitable person getting through a difficult moment in her own uniquely constructive manner. Gauch's wry, understated humor is charming; Primavera's sturdily realistic pictures subtly deepen understanding of Christina's mixed emotions. A cheerful, wholesome addition to the new-sibling shelf.
