since my grandsons have so many grandparents and greats as well, I am nana to my gsons....and when my daughter had steps sons i was also nana.....grammy is what my one daughter calles my mom and when my other dd writes about her grandparents (my folks) she calls them gpeeps lol so there are lots of ways to call the grandparents... and kids will always find their own names for you and as long as they love and hug and kiss on you etc will answer to whatever i am called...
