"Ten little babies, sitting in a line" (in a carriage, strollers, and on the ground); a folded page opens to reveal that "One toppled over. . .then there were NINE." And so on, with the nicely individualized tots engaged in varied, ordinary, but interesting activities until the last goes "Off to bed." Kopper's illustrations are realistic, lively, and unusually attractive. Just right for toddlers.
