I think every family does presents differently and what works for them works for them. I think a lot of people will be mortified at how we do Christmas so waiting to be flamed, but here goes:
In our family we buy for adults and children. Just been going through everyone to make sure no ones been missed (yes I missed 3!) and the money spent varies.
E.g: I've spent between £30-£40 on each of my ex sister in laws, between £30-£80 on ex mother in laws (there's 2 lol), £40-£120 on ex partners, £20-£30 on ex partners girlfriends and children and then there's my parents, my siblings, our friends, neighbours and their children.
It seems a lot, HOWEVER, I and both my children get gifts from all of these individuals too, so I buy a gift from the children and a gift from me to them. I know not all families work like this, but it's how we've always done it and it works for us.
But my youngest on his dad's side is the only child, so has 3 aunts and 2 uncles who spoil him rotten. And my eldest is now in a blended family at his dads and is 18, so he's just money and bits as he has everything he needs. (We're at the stage of persuading him to put money away for uni in 9 months!)
People don't get tat, just for the sake of it. Gifts to us are things we've maybe mentioned throughout the year we like, or that the person thinks we would really like. E.g- my youngest is into a certain clothing brand so has a new hoodie, t-shirt, hat, joggers and a bag off his grandmother. One aunt is buying him an Amazon echo because he keeps pinching the one out off the kitchen, I've bought one sis in law a pandora charm she said she liked whilst out shopping, my eldest a new keyboard for his p.c off his step uncle, I have new perfume off mother in law that I mentioned I liked, my best friend has a book she said she liked but could not justify paying the price for.
We also do not do the 'I spent £40 so you have to spend it one me' thing. If one thing costs £10 and another £50 then so be it. But people only spend what they can afford.
We just like to show each other at Christmas how special we are to each other, and as we don't do the one big Christmas Day (as there is so many families) we show that love with a gift.
And as for my kids this year, eldest 'I don't want or need anything' and youngest 'I only want an Xbox game and some money'. So they've both agreed to having some bits in their stockings and they are going to have money for the sales and both buy new bits for their gaming pc's, they have every thing else they want, so this year will be the fastest present opening time ever in our household! The family presents will take longer lol
