All 3 of mu grandkids call me something different. My granddaughter calls me Nanna, her brother calls me Nina. My other grandson calls me Naynays. My husband is Pappy to the brother and sister and Parpars to our other grandson. You could just wait and let them name you. I think Nanna is what Kayli could say from her parents calling me Grandma Danna. Her other grandma is Mim, or her version of a shortened grandma Missy. It is a whole new wonderful world!
