To not want to leave the house one day a year?!

[Inittwowinit]

DH and I have two children - a 2yo and a 4mo. In laws live 1.5 hours away. I have said that I want is to have Xmas Day at home, rather than at the in-laws with their extended family. I don't want to be dragging our two year old away from exciting new presents to stick him in a car for three hours to see many people he doesn't really know. It will be manic and stressful for me too.
I've said that I'm happy to visit family any other day - just not Xmas day. I get on well with my in-laws, so that's not an issue. My family live abroad so I won't be seeing them. AIBU to say that regardless of whichever far flung relatives will be present we're staying home on Xmas Day itself?

I can see that driving 90 minutes each way to celebrate Christmas Day is a bit of a pain. However, for me Christmas is about the family getting together rather than all the other peripheral, commercial stuff. But that is my feeling and yours is different. If it really is making you anxious and unhappy then perhaps it is better to stay at home as you won't enjoy it and that feeling is likely to be conveyed to everyone else at the family gathering.
