My 2 1/2 year old grandson calls my husband "Dude". My sons and my husband are all die-hard surfers, so it fits.

When our first granddaughter was born my son informed us that she would call us Mammy and Pappy. I had my doubts until I heard her excitedly call me "Pappy" for the first time. Now I wouldn't want to be called anything else.

A grandchild that comes up with a name that just ends up sticking is different then grown folks insisting that their grandchildren call them something than what they already are.
My mother got her wish only because her first grandkid, my daughter, called her Mi-Mi since she was one year old. It just kind of stuck, fortunately enough for her;-) She did try to get her to call her something else though, but it didn't work out;-)
