Our Christmas has never been particularly OTT, and we enjoy it as it is, so won’t be re-thinking it.
As for the ‘Christian’ bit, a lot of people, inc. me, who aren’t at all religious still enjoy carols and the Nativity story - to some extent it’s woven into our culture. My dd and SiL aren’t in the least religious, but they still took little Gdcs to the children’s crib service at the little local church, where so many children could dress up as angels, Wise Men, etc., take part, sing traditional carols, and enjoy it all.
It was lovely, and if a lot of those who attended the service piled in afterwards to the lovely old pub just across the road for a glass of mulled wine, that’s part of Christmas for quite a few of us, too.
