Here is an old fashioned but very sweet book that is always a hit with my preschoolers. Although the illustrations are dated, there is good preschool-level suspense when Danny goes into the woods to talk to a bear.
Danny wants to buy a gift for his mother for her birthday. He asks a hen, goose, goat, sheep, cow and then finally a bear what to give his mother. The bear gives the best answer, a hug.
