Our lead up to Christmas is relatively stress-free as we don't shop for gifts in super busy shops, or have to listen to Xmas songs from Halloween to New year's whilst shopping.
Christmas Day is us with our adult DC's having Christmas dinner round an seasonally decorated dining table, and because it's the kind of family we are I guess, we always make these times fun, with plenty of humour, also wine helps.
We do gift our dcs some money so that they can treat themselves to something, when they want.
What we have also done is give the gift of giving, a donation to a worthy cause, in the name of the gift recipient.
It feels good to help others,or animals in need, no matter how much or how little you can afford.
One thing you could try @Mrsmunchofmunchington is something a friend of mine now does.
They volunteer on Christmas day where Christmas dinners are being served to people who are alone or who wouldn't have a Christmas dinner otherwise.
This friend has said that volunteering has made them happier over the Christmas season than they have felt in a long time.
Also forget about Christmas cards, for the most part physical cards with a signature on the bottom are filling the tip, and a thing of the past.
