I don't know what other families do but we hang out and eat. In between it all, often involves group shopping, naps, XBox or wii, baseball, puzzels, board games, venting, and lots of love, care, nurturing. 
I made vegan lunch and dessert.
Lunch flowed into afternoon tea and flowed into dinner. Dinner my sister Helen and Brother in law Andrew put up a Japanese meal. Everything was wonderful. Then we opened the presents and then we had more dessert and tea and coffee.
