A.A. Milne's books for children - "Winnie-the-Pooh," "The House at Pooh Corner," "When We Were Very Young," and "Now We Are Six," with the Ernest Shepard illustrations (not the Disney versions!) - all of them have been favorites of mine since I was 4 years old, and I give them as gifts to all my grandchildren and great-grandchildren, and I hope they will give them to their descendants also!  My only misgiving is that the volume may be too heavy for preschoolers to hold.
