Each year C and I have cut oranges, lemons, limes, and grapefruit to decorate our tree. We also string cranberries. We started this tradition from our friends Barb and Dan who celebrate the holidays with a Yule tree. When the holidays are over and we take down our tree, we hang the fruit outside for the birds and animals. This was the first year that K "helped" string the fruit. He did more squeezing of the fruit and popping of the cranberries then anything else, but I think he had fun.
