The one thing DH makes sure to do is to watch National Lampoon's Christmas Vacation with me one night in December. We also watch White Christmas---DD watches that one with us, usually.
I've gone with my mom & DD to Fantasy of Trees every year since DD was born. I have a thumbprint ornament of each year, & my mom has a photo ornament of our trip. Mom is having double knee replacement on September 28, so we're hoping she's well enough to make our trip to FoT on Black Friday this year!
DD & I make a treat for Santa every year on Christmas Eve, & DD throws reindeer food in the yard.
