DHs two eldest grown up children live overseas with their families. They are both very well off, we struggle. Every year they buy my three girls (2 stepsisters and 1 half-sister) a very small present each, a small purse or keyring etc, which I am grateful for. They also buy a bigger presents for their own children from Granddad (DH) and instruct him how much to put in their bank account to cover it. We don't get to choose what the gift is or how much to spend and we are struggling to scrape up the amount asked for.
I am all for DH buying his grandchildren presents and accept that this is a very good way of doing it, cutting out postage etc, but still, the way it is done seems a bit off to me.
