The Big Snow by Berta and Elmer Hader
The animals of the forest are getting ready for winter as the geese fly south. Deer, raccoons, mice, ground hogs, birds, are all preparing. Then, just after Christmas, a great snow falls. Hunger sets in, but a kind old man and woman put out food for the animals and birds.
That's all. Nothing else happens. It's a lovely peaceful book of the natural world and its intersection with our world, when we care to notice. After reading it, my children always want to put out food for the birds. They've never been disturbed by the realization we live a bit farther south and don't have any big snows that last all winter. (We do usually have one or two big snows that melt away.)
