Not to worry!
We gave up dealing with all that years ago! We (my husband and I) now only get the small children something as a token. And they like it just as well. Cracker Barrel has the old timey toys and the kids love them. As they get older then homemade gifts to and from them is the thing. Choosing toys for the unfortunate is the focus of their holiday season since the have so much anyway.
For decorating, it is age appropriate and with the help of the children. Very simple things like construction paper, glitter and glue to start and they make their own felt stockings. They connect with last year's Christmas cards cut out and glued on the back of clothes pins and stringing popcorn to hang with candy canes. There is a recipe for cinnamon and applesauce dough that is rolled out, cut into gingerbread men and shaped if you don't want the real gingerbread men. They have to be done ahead but can be decorated just before you hang them on the tree, and they smell wonderful!
I know you have collected lots of things over the years but soon it is time to "gift" them to friends and family. I cook the turkey the day before, debone it into the large crookpot and cover it with thin gravy. Dinner it pot luck and buffet style. The turkey leftovers are just as good on day 3 as day 1. We spend our time with each other and out of the shops and malls. Who are you trying to impress?
This season is now my DH's favorite time of the year instead of the most avoided.
