I got DS a small present to give his grandmother (father's side) but not sure how to address it - her other grandchildren call her I think "Avo" as in grandmother in Portuguese - however when I asked DS's father how I should address the present he said 'grandma'????
Why should DS refer to her differently than her other grandchildren? To me it doesn't seem right and I really want to put "Avo" just to make a point.
What would you do?
