Christmas Eve
My office is open until 2:00 and my husband's is closed. He is home with the kids and gets them bathed and dressed and loads up the car with all the stuff we'll need for the long day/night. Then he takes the kids over to his mom's house after lunch. She and my FIL host a big party that night, we can't go. She at least gets to see them. We head to my parent's house before 4:00. We eat, play games, open gifts, etc. and we are home by 10:00.
Christmas
We open gifts and play with our favorites and I pop an egg bake in the oven and crank up the xmas tunes. We are on our way to my in-laws by Noon and we hang out there until 6:00 or later.
We have two post-Christmas events; one week or so later with my FIL (DH's parent's are divorced) and then w/ my mom's extended family sometime after the new year.
Busy Busy Busy. Wouldn't have it any other way. Because the other way means my family is dead and I have no where to rush to.
