These threads appear every year & I find them totally fascinating!
I was raised in Ireland in the 70s & 80s in a practising Catholic family & Santa was a huge part of growing up for us.
I think, from what I've read here over the years, that Santa was / is far more universally accepted there than in UK.
I don't think the general population of Ireland is massively traumatised by their collective childhood belief in Santa at all.
When I was growing up We ALL believed fervently & for far longer than seems the case in the UK. I was at least 11 before one of my older cousins told me & she also told me it was our job to keep it going for our younger siblings. Which we did. We have a large age gap in our family & i was still writing letters to Santa with my youngest sibling when I was 17 & none of that bothered or traumatized me at all.
Times were hard & money was tight for a lot of people in ireland in the 70s & 80s & yet parents created this time of wonder for their children. A pp said that the excitement of the build up & the lying awake on Christmas eve in anticipation listening for sleigh bells meant even the most modest gifts were viewed through the lens of the magic of Santa & I don't ever remember being disappointed by anything I received or comparing it to what others got. And I know there must have been lean years for sure.
My dh grew up in an English home where Santa / Christmas were not really celebrated. V little effort was made at all. He didn't 'get' it when we met. He celebrated a few Christmases with my family before we had dc of our own & he was happy for us to continue my traditions & now he's the biggest fan of us all.
The traditions are more than Santa- they're the rituals we carry from year to year & give us a real sense of belonging, of family, of comfort. Our Dc love them too & even now as teens won't consider deviations.
For my dh who never had any of that growing up, it's something he cherishes & he gets quite sentimental at Christmas time.
We've never told our dc there's no Santa! We carry on every year exactly the same ad the last - stockings are hung, mince pie & whiskey is left out. Presents appear overnight & stockings get filled.
