Buying an artificial fiber optic tree will eliminate the need for stringing lights and hanging ornaments but that doesn't mean that you can't create your own family traditions to add to the tree. Maybe choose one ornament per year, as a family, to add to the tree. This way your tree won't be overcrowded and each and every ornament will be memorable (remember to date all of the ornaments).
A long-time Christmas tradition is to place an angel or star on top of the tree. Make it a family tradition to pick a new crowning object every year to put on your tree. Remember to take a picture of each one so you can document them (this would inspire a great scrapbook). Be creative and make your own family traditions!
