I am called Nana by gd#1 and gd#2 is only 3 months so I don't know what I will be called by her. It's their choice. I did have a great nefew call me granny nanny once, but I set his straight on that one. (Had something to do with being called Nanny Goat as a child) When we will little we called my dads parents by their last name gm (last name) and my mom's parents by their first names gm Jeannie
