I am Nana. It's a first name. I'm extremely close to my grandchildren and Nana is the sweetest sound I ever heard when they call for me. My ex-husband is Poppy. My son-in-laws parents are Grandma & Grandpa "Insert last name here". They are formal grandparents. But then - they have a bunch of grandchildren. I just have the three Magical Creatures. I thought I would be Meima as that was their mother's nick name for me for most of her adolescence and young adulthood. She decided to keep that special nickname just between us and gave me Nana instead. The upside - it's really easy to say and at 18 months old my oldest granddaughter would get her phone to FaceTime me - chanting "Nana nana nana..." at her mother. I have two close friends - one is Gigi and the other is Mimi. We are quite the trio. ;)
