My oldest son and his family live over 6 hours away so we don't get to see his family very often, usually 3-4 times a year. He has 3 kids, all boys, ranging in age from 12 to 15. Every year for their birthdays, we send a card along with a $50 check. We've done this their entire lives. We also send a check to my son and his wife on their birthdays. The thing is, my son's wife is the only one who ever thanks us for our gift. She will always send us a nice text or a hand-written note, thanking us for the gift and telling us what she is going to do with the money. From the other four, including my son, zip, nadda. So for the next year, I'm saying that with the exception of my DIL, we should cut them off. Send a nice card for their birthdays, but no money. If anyone asks about it, we'll just tell them that we are done sending money that is not appreciated. My wife disagrees. She thinks we should just keep sending money and not say anything about it. She doesn't see it as an issue. I see it as a lack of character. What would you all do?
