We love The Kissing Hand by Audrey Penn. The book is "for any child who confronts a difficult situation, and for the child within each of us who sometimes needs reassurance." Great story and cute illustrations.

Summary
School is starting in the forest, but Chester Raccoon does not want to go. To help ease Chester’s fears, Mrs. Raccoon shares a family secret called the Kissing Hand to give him the reassurance of her love any time his world feels a little scary.

Mrs. Raccoon tells her son "I know a wonderful secret that will make your nights at school seem as warm and cozy as your days at home." She then kisses his palm, and Chester feels the kiss "rush from his hand, up his arm, and into his heart." Whenever he gets lonely, she advises him to press his hand to his cheek and "that very kiss will jump to your face and fill you with toasty warm thoughts."
