When my kids were smaller, I would make sugar cookie dough and set them up with cookie cutters
and molds and let them go crazy while I worked on Thanksgiving dinner. Once they were done preparing the cookies, I would pop them in the oven and after they cooled, I would let them decorate with icing and sprinkly things. Then they would be added to the dessert table for everyone to enjoy. The kids enjoyed it and it kept them occupied so I could concentrate on dinner.
