They are my dh's brother's children. We see them rarely, maybe once every 2 or 3 years for a family event (like a golden wedding anniversary or a christening etc). Dh is not close to his brother and bil wife does not like travelling (they live about 3 hours drive away from rest of family) The girls are now 18, 21 and 22 - so not children anymore, but they are still our nieces.
We have 2 children - 15 and 21. They still get a present from their aunt and uncle, but wouldn't miss it if they didn't. I was going to phone sil and suggest that maybe it was time to stop buying, after all they are adults now. I said to dh that if they had phoned us to suggest it we wouldn't have been offended.
But I chickened out cos I felt that it was to awkward to phone someone that I only see every couple of years to suggest this.
AIBU? They are our family. And if I'm not, how do I go about it?
