It could be that they have all the "stuff" they want and need - Maybe they think it's very difficult to get you anything meaningful -
However, in our family - which isn't very big - everyone felt major relief when the gift EXCHANGE was stopped.
Our kids had no idea of what to get for us - and everyone seemed too busy to contribute time/labor to anything.
Our kids are all around 50 - and they have no "need" for anything we can afford - what daughter wants is child supervision once in a while - but her kids are so booked up that it's hard to find a few minutes when they are unscheduled.
Perhaps your urge to give could be to transferred to adopt a needy family and dote on them. Maybe you could all go together and get someone "something special/needed" that he/she probably would not be able to get because they were poor. Like a new refrigerator or microwave oven -
I kind of understand that you feel that your parade is being rained on. You could go even one farther, and say "Good idea - no Christmas gifts for any family this year - We will do something special for ourselves with that money." You could "make it up" for birthday presents if you had severe gift giving withdrawals.
Do you (all) still get together during the winter holiday season? Maybe that's enough for the rest of the family?
