Mouse and Mole and the Christmas Walk by Doug Cushman
There is a lot to admire in this book. First of all, it encourages a holiday with a low ecological impact as Mouse and Mole make their own edible decorations which they put on a tree out in the forest (rather than cutting one down). It encourages experiences and the joys of sharing rather than the consumption. The illustrations are simple but charming. And the bottom of each page has brief, mostly scientific, facts about winter to sustain the interest of older readers.
