Dd was not born till I was 35 so I had had a lot of child free Christmases before her and I loved them all. My family made traditions as myself and siblings grew up that probably could only be done in a child free house - visiting friends on Christmas Eve night for wine and nibbles, sometimes midnight mass AT midnight, home to eat some of the ham my mother had cooked. My parents had family friends who always called in for a few drinks with them.
Once everyone was gone and the house was just back to the immediate family we then had a glass of bubbles together and opened our presents - it was after midnight so technically Christmas Day! My parents replaced stockings with Christmas sacks and we had lots of small and thoughtful presents and it was so lovely to have that hour or so, just us - parents and grown up kids in our 20's. Christmas Day we hosted wider family, grandparents, aunts, uncles, cousins and it was busy and loud with lots of wine and champagne.
Then I met dh and he spent a couple of Christmases in my family home and loved it , it was totally different to christmas in his family.
Once dd was born I took over the hosting and Christmas became more focused on her and my parents loved it all, reliving memories of us as children. My siblings did not have children at that stage and some years came to join us, other years travelled, and then they met their other halves they went to inlaws etc but there was always an open door to ours.
Now dd is a teen and we're slowly moving back to the more adult style Christmas. We in a sort of half way stage at the moment. 'Santa' still comes and fills stockings and leaves presents and surprises and we all keep up that tradition. For now. My parents still come to us, siblings are away this year and have small kids of their own.
I can see us coming out the other side of kids christmas in the next year or so and am looking forward to that very much. I intend to travel if and when financially viable - Christmas in New York with dh and mid-teen dd - happy days. And my parents get to enjoy Christmas with siblings and santa and young children again
