Joyce Sidman is one of my all-time favorite poets. Her books concentrate on the natural world and evoke beautiful images. Coupled with excellent illustrations, these poems are great for sharing with young readers, or for paging through with a cup of tea.
Sidman's latest effort, Before Morning, is illustrated by Beth Krommes!!! (Caldecott award winner, Beth Krommes, that is.)
Check out Sidman's earlier book, Winter Bees and Other Poems of the Cold. In it, Sidman, examines how various animals and insects survive through the cold months.
Doug Florian is an American poet/painter whose poetry books delight kids everywhere. Winter Eyes is one of my favorite Florian titles. The words and pictures remind me of brisk cold skies and the coziness of winter sunsets. His palette is perfect.
