Where do you live OP?
I only ask because where I am, there are a lot of free/very affordable Christmas things that go on. There's a chap that has a roadworthy sleigh and mechanical reindeer that lift up, like magic. He dresses as Santa and a couple of nights in December he tours around the streets blasting Christmas music and then stops in a designated place. Kids can have a cuddle and pic for free, or collect a small gift for a few quid. All the proceeds go to local charities and its honestly so lovely.
I caved and made a FB account when DD was a baby and follow local businesses, soft play, Families First page etc, amd just take a couple of minutes a day looking at what is available
We're doing breakfast with Santa, but it's only about 12 quid and adults are free if not eating. Same with Christmas railway, but we are 10 minutes from the seaside and this train runs anyway, so it's fairly inexpensive for the experience
I think maybe location is key and we do live in one of the most impoverished parts of England, so I'm guessing we pay a fraction of what you would for similar experiences down South
I do the Elf too, but honestly it was like 3 quid, it'll last bloody years, then get donated and it take maybe 5 mins to scroll Pinterest to get an idea and I only do ones that I already have the stuff to do
I will say though, I only have 1 child and know this magic will only last a few years, so maybe that colours my view
I don't generally have a strong opinion on xmas one way or the other. I'm an atheist, we're certainly not loaded, but mine is still young enough that Vinted presents are absolutely amazing to her, we're a long way off from expensive gadgets!
Ultimately I'll cringe when DH pulls the bloody Perry Como record out amd I know I'll have a few late nights organising stuff, but it doesn't overly stress me
And I will be working the Christmas night shift too, but drinking has never bothered me and DD will be going to bed as I go, so I'm not too fussed
But, please don't make yourself genuinely unhappy doing this stuff, because that will bleed down to your kids, they tend to be intuitive little things
