All of our kids are grown, and they all do Christmas dinner with all their assorted inlaws so it is tradition in our house that everyone comes over Christmas morning for breakfast. We keep it pretty simple, they can come over as early as they want, breakfast is served at 10 am. Either before or after breakfast depending on when everyone gets here we open presents. The one rule we stick to is that everyone must leave by noon.....then DH and I have the rest of the day to ourselves. Its always good fun having all 12 grand kids plus all the adults here at once, but by noon I am ready for the peace and quiet!
