This really cute story is told from the perspective of a young boy who really wants a brother.  When mom and dad present him with a baby sister, he assumes it is a mistake, and sets out to rectify the problem by finding someone willing to trade, but every time he finds a prospective trade, there’s some flaw that makes him realize his sister’s not so bad.  At one point he misunderstands the purpose of a baby-changing station, much to his disappointment.  While searching for over a year to try to find a suitable candidate, he learns to appreciate his baby sister’s finer points, and finally gives up the search, only to be told a new baby is on the way.  The illustrations are charming.  The topic is one many kids can relate to.
