Then don’t! It’s okay to tell your kids that you couldn’t get the overpriced stuff on the Xmas list.
It’s about teaching them to manage expectations.
Get some accessories or something (someone mentioned socks, the pencil case, a t shirt) but when it’s something that’s big ticket prices for what is essentially a trend that in a few months will be gathering dust in a toy box…. Just don’t prescribe to it.
kids need to learn and learn young that we aren’t bottomless money pits, that everything has a price and that somethings are just unreasonable or unrealistic. And not just at Christmas but all year round.
Re Xmas we actively curate our DCs wish lists. If there is something crazy on there…. Whether it’s expensive, ugly, unattainable, would not let my kid be seen dead in, etc etc we just look it at it, laugh, make a joke and say oooh not sure about that you can out it on but can’t see it happening.
When younger we also went with the line that “we send Santa money so Santa can only bring what we can afford” which helped keep the magic of Santa but with realistic attitudes
now teens they still write lists so we know what they want, and they still stick some stuff on that’s crazy (£24 lip gloss ?! Fuck off) but it works brilliantly because they know that a reasonable list means they actually get most of what they want…. Which is great
Honestly the kids have never ever been left upset because they didn’t get something.
