DD is 14 and we've been doing it all her life.
And in our case, it follows quite a spiritual part of Christmas for us as a family (lighting the Christmas candle and reflecting on the good and bad of the year finishing, and those no longer with us, finishing with a family prayer).
The funny thing is, while I have talked on MN for years about this, I don't think I have ever talked in RL outside of my immediate family (the ones living in my house I mean) about it. Because it is part of OUR Christmas, not anyone else's. And I have never taken a photo for myself, let alone SM purposes, of it.
But it's like a lot of Christmas things.
Some people do a lot, others do a little.
Some people have a very religious season, whereas for others it is a very secular celebration - and there are people at all parts of the spectrum in between.
Some people like huge family gatherings, some have small family celebrations, some want to spend it alone, some have smaller or larger gatherings of friends rather than family etc.
Some celebrations involve the roast turkey and all the trimmings, some have goose or beef or lamb, while others have a takeaway or a special meal that is festive to them and that they enjoy.
Some families have huge amounts of alcohol, others have none.
Some families have large tubs of Quality Street, some enjoy handmade truffles (or even homemade!), while others don't really eat chocolate or sweets.
Some love and some hate trifle.
Some only do small gifts, some only do gifts for DCs, some do Secret Santa exchanges, some do extravagant gifts even for adults.....
In some houses, Father Christmas/Santa/Santy/St Nick brings everything to DCs. In other houses, he only brings the stocking. In some houses, he brings a stocking and a (or a few) big gift(s), but all the presents under the tree are from various other family and friends. (In the first, "he brings everything" category, I mean literally that - there are no presents from DGM or Aunty Jane or Cousin Eric under the tree for DCs, even if the DPs in the house get presents from those people - Santa has brought everything even what had been from DGM/Aunty Jane/Cousin Eric etc).
Everyone is different.
Every family has different budgets, traditions, levels of faith, school and other local celebrations to facilitate/attend etc. Different places have slight nuances on how they celebrate or what a seasonal character might do (I know 1 Santa who arrives on a lifeboat every year, and another who goes to a local school on a fire truck, but another who just appears from behind a door into a school hall from the Principal's office....and some of those Santa's give gifts, or have an individual chat with the DCs, but others just enjoy time with the whole group of DCs telling stories and organise carol-singing by the whole group).
Everyone is different.
Do what you want and what suits your family circumstances, beliefs, budget and levels of stress.
Don't do more than you want or can afford to do.
The same as in every other part of life (holidays, weekly food shopping, choosing a school for DCs, etc....).
And if you can, accept that we are humans, so while we are quite similar, we are all different, and it's better to celebrate those differences that to rail at them.
