In this house, Yes. My son Darby is PoPo. Daughter Brianna is Nanna, Daughter Emily is Bethany Marie. Think the only one with out a nickname is Kimberly. She is simply Kimmy. In public.
At home My children are refered to as: Pumpkin butt, Dehlila, Midget, Georgous, Beautiful, and Love.
My husband NEVER calls me by my name, and the whole internet community knows me as Clover.
