What is/was your Christmas morning like? Organized, or a free-for-all?

It’s Christmas morning, and the kids wake up at some insanely early hour to see what Santa brought. Do they leap out of bed, run to the Christmas tree, and start wildly ripping open presents? Or, does everyone sit down and take turns opening gifts one at a time? What is the present-opening etiquette in your family? Either now or when you were a kid, whichever you feel like sharing!
