Children's books are my addiction, and Christmas books are some of my favorites!
The Christmas Cat by Efner Tudor Holmes, illustrated by her mother, Tasha Tudor (Actually, ANYTHING written or illustrated by Tasha Tudor has a distinctly non-materialistic bent to it - her The Night Before Christmas was a snuggle up and read together every Christmas Eve tradition in our family, even through my high school years) (A charming tale of a little gray cat, lost and abandoned in a blizzard, and the Christmas magic that brings him into the lives of two children.)
The Wild Christmas Reindeer by Jan Brett (Focuses on patience and working together - and the reindeer's names are different from the usual "Dasher, Dancer, Prancer, Vixen etc", one named Heather!

: )
Jingle the Christmas Clown by Tomie dePaola (Great recipe for cookies in the back of the book - I've often read this book with my class and then we've used the recipe to make star shaped cookie cutter cookies.)(Staying behind when their circus moves on, a young clown and a troupe of baby animals put on a special Christmas Eve show for an Italian village too poor to celebrate the holiday.)
The Trees of the Dancing Goats by Patricia Polacco (On the family farm in Michigan, Trisha and Richard watch as Babushka and Grampa prepare for Hanukkah in their native Russian way, hand-dipping the candles, carving the children gifts of little wooden animals, cooking the latkes. When scarlet fever debilitates their neighbors, Trisha's whole family pitches in to make and deliver holiday dinners and Christmas trees (decorated with the children's wooden animals). Polacco's characteristically buoyant illustrations embody the joy of holiday traditions even as her robust storytelling locates the essence of that joy in sharing and friendship.)
Christmas Tapestry both by Patricia Polacco (Jonathan resents his Baptist preacher father's reassignment from Memphis to a dilapidated church in Detroit, and he's dismayed when damage from a blizzard ruins months of planning to restore the building in time for Christmas Eve services. But the elegant-looking, bargain-priced tapestry he and his dad purchase to cover the damage miraculously brings about the reunion of an elderly Jewish couple separated decades earlier during the Holocaust.)
Night Tree by Eve Bunting (A family shares their own Christmas Eve tradition, leaving their conventionally decorated ranch house in Dad's pickup to deck a live tree in the woods with popcorn and fruit for the forest creatures.)
