AIBU in resenting my Mother, she does not send any of my children birthday cards, presents or even messages on their birthday, yet she spoils my brothers little boys rotten, one of my children and my nephew were born two weeks apart and she still doesn't acknowledge my sons birthday, I get it that I have a lot of children (clue in the username, lol) but I don't expect her to buy my older 5 gifts, a card or a phone call would be enough for them they are 17-23, but my younger three sons are only between 3-8 (I have a DS in heaven).
Am I expecting too much for her to treat all the younger ones the same way?
