Mommy thinks it would be a good idea for Caillou and his friends to exchange their toys, but Caillou has reservations about giving up his own. Caillou quickly learns important lessons about working within a group, the value of playing well with others, and ultimately the benefits of sharing. Focusing on the psychological aspects of a child's first years, this educational board book offers a convenient and fun way for parents to directly engage their own children, through the illustrated world of a popular PBS Kids television character.
