More than old enough to understand it's rude to expect gifts, and also old enough to understand why their aunt isn't doing gifts. She's not giving to charity on their behalf, she's donating instead of gifts.
Children do get excited at presents, esp from their own parents, but I do feel children should know it's a privilege and not a right. DD knows she's very lucky to get the things she does as there are so many children around the world who don't have family, food, home for the whole year, let alone a pile of presents at Christmas.
OP handing a card on the day saying "here's your Xmas gift, it's a £50 donation to the local hospice/oxfam goat/ sponsor a donkey etc"
And saying five weeks before "I'm not doing gifts this year because,,,,, and please don't buy us anything in"
Are two totally different things. (Although I wouldn't be angry at the first either to be honest, dh says he'd feels let down but would absolutely not say anything or fall out with anyone) if people buy ops son gifts that is their choice, OP should not feel awkward at all, and one person not doing gifts is hardly going to leave anyone deprived, or change Christmas, everyone else is still doing gifts.
I've just come home from a funeral and watched 6 young heartbroken children bury their young father, on Xmas eve. It's put a lot of things in perspective for me, these children really are losing out, their Christmas has really changed, forever, as has the rest of their lives, not speaking over a few gifts seems even more ridiculous now. I hope you both can make up and enjoy Christmas OP.
