Grinch-mas is an annual holiday tradition inspired by Dr. Seuss’s classic How the Grinch Stole Christmas! that encourages readers to “grow your heart three sizes” through the celebration of family reading, giving from the heart and community spirit. National Grinch Day, December 1, kick starts the 25 Days of Grinch-mas.

During this time you can meet the Grinch in person at a local event, go Home for the Who-lidays with fun family crafts, and find the perfect gift for a Cindy Lou Who by you in the holiday collection.

Plus, check back every day of Grinch-mas for a new good deed: each guaranteed to grow your heart at least three sizes!
