My granddaughter is starting to try to communicate. It will be no time at all before she starts talking. So, I need to decide what I want her to call me. I called my moms mother grandma, but refused except that I could have two grandma's so I called my dads mother Nana. Being the mutt I am... English, Irish, Scottish, Russian, Polish, German, Cherokee and Choctaw Indian that I have many languages to choose from. I'm soooo confused. What do you call your grandma?
