Oliver Soliver does not love the new baby. While jealousy is not a new theme in picture books, rarely have the dynamics of sibling rivalry been seen through a newborn’s eyes. And what big, frightened eyes they are as the baby navigates the world according to Oliver. Oliver is the monster sibling who torments the new arrival. But forget traditional noogies and wedgies and painting a face in permanent marker. Oliver Soliver has more sophisticated skills, all slyly disguised as lessons for his grateful new brother. But this baby has a surprise for Oliver. And Oliver is not going to like the reciprocation at all.
