When our first grandchild was born, my husband and I were not yet married, and she called me Kaky (my name is Kathy), but that name stuck; all the rest born after her still call me Kaky...my husband is Pawpaw...I think naming grandparents is an honor the first grandchild has the privledge of doing. Most of the time, the grandchildren born later all use he same 'title'. However, since what they call me is unique, I absolutely love it!
