My granddaughter was still at the stage of calling everyone "dada". I told her mom I wanted to be called by my first name (she wouldn't have that!) Nana, or Grandma. I have been called Nana ever since. My children and grandchildren call my mom, grandma, called my dad, gramdpa. I called my grandparents, Mawmaw and Pawpaw, (mother's side) and Papa and Logie (dad's side).
