To suggest we stop buying presents

[Moreorlessmentallystable]

Every Christmas buy presents for 12 kids in the family. My kids are very appreciative of the presents as they are not over indulged, but some presents are literally used once then never played with again, they also got vouchers for more toys, etc and A TON of sweets ( I don't like this as it's difficult to get them to moderate their sugar intake), one of the families really puts zero thought into the gifts and for the 4th year in a row has gotten them the same thing (think a bunch of pound items stocking fillers to each kid), as I said others do vouchers which end up with the kids wanting to go shopping straight after Christmas when I much rather be spending some quality time with them instead of doing yet more shopping. I sometimes feel we could just stop buying each other's kids and just have less "one use presents"... I feel as they are getting older they are starting to like bigger/more expensive items and every family would be much better just better using the money on their own kids to buy the things they really want/need, instead of buying 12 cheap presents. There is another issue with some of the families having only 1 kid and one having 5, so really unequal in that sense too.

Suggest a secret Santa with agreed budget? Kids pick for their person - hopefully know each other well and can make suggestion of what to buy. Reduces cost, stress and amount of unwanted presents?

In a similar situation we did a not so secret santa. Each family bought the same number of presents as children in their family, for other children in the same circle of friends. We drew names out of a hat, though put the name back in if we drew out own child. Each child got 1 £10-15 present rather than several smaller presents. We also bought one decent birthday present for each child between the group, (each family excluding the parents contributed) including a bigger present at 18, then birthday and Christmas presents stopped.

YADNBU.
I stopped this a couple of years ago and it was the best decision. Christmas shopping became far less stressful. It is so difficult trying to find appropriate gifts for other people's children especially when you don't know what they already have or what their current interests are.

Why not agree to buy 1 present from all , each family donating an agreed amount ie £10, to the parent who Ian responsibile for buying their child’s gift which says it’s from all the aunts/uncles. That way the child gets one higher value presents from all the family instead of lots of smaller ones.
I have a friend who is one of 6 and they do this until child is 21 , makes sense to me
