William thinks it's no fun having a little sister. Not only does Emma take up all of Mom's time, but she wants to play with William's toys -- especially his favorite, Spotty Cat. But when Emma is ill and nothing can make her stop crying, William has a brilliant idea ... This delightful second book about William, following "See You Later, Mom!" describes the pain and pleasure of being a big brother with a little sister, and shows in a gentle and humorous way that it is good to share!
