My husband works 60/70 hours a week and I work 12/15.
We decide on what we are getting for the dc together and either go out Christmas shopping together on a weekday in December or order online - either of us will do that.
He organises, buys and wraps all the presents for his side of the family and delivers them to them.
I do likewise for mine.
We share writing the Christmas cards 50/50.
We go out and buy the Christmas tree together as a family and usually the dc and I will decorate it.
I usually think about any other decorations we might put up - buy a wreath, display the cards etc.
I do most of the food shopping online but he, me or both of us will go out and do the last minute shop at Sainsburys on the 23rd or Christmas Eve.
We wrap the dc presents together between us.
On Christmas day I usually cook dinner but the prep of veg is a joint effort and my mum joins in with that. He pours drinks and tidies up unwrapping mess, lays table with the dc, organises breakfast and gets the dc washed and dressed.
I suppose someone somewhere thinks he deserves a medal for all that.
