My late paternal grandparents did a similar things with me and my siblings, basically the girls got gifts and the boys were left out! My mum put that matter straight by saying if all her children can't be treated the same then none of us should have anything, now I'm a grandmother myself I completely agree. My maternal grandmother was fair to the last penny and tended to be over generous so we had to gently remind her to not spend quite so much. My late mum was the same, fair to the last penny, and here again we had to gently remind her to spend less. However, father was different, he clearly had favourites but we let it go as the grandchildren were growing up and they all understood. So, Pracatan, don't try to push you mum into spending where she doesn't want to, keep to your own budget on those that matter to you. I don't want this to have sounded a bit double sided, merely trying to say " let mum spend her money her way " . I don't see that it's your responsibility to make excuses for her, do that and it puts you in a bad light with the children that go without.
