Little Bear's Visit by Else Homelund Minarik
Little Bear goes on a visit to see Grandmother and Grandfather Bear. They each tell him a story. Grandmother Bear tells the story of how Mother Bear took care of a baby robin. Grandfather Bear tells the tale of a goblin being chased in the woods--by his own shoes! Before he even realizes it, Little Bear is exhausted from his visit.
The Little Bear books are definitely classics for a reason. The stories are short, simple, and fun, and Maurice Sendak's illustrations are great as usual. This is most definitely a book that will be around for years to come.
