Nicknames for a great-grandmother include Gran, Granny, Mammaw, Nana and Mimma. To avoid confusion, choose a nickname for a great-grandma that is different than the nicknames given to the child's other grandmothers or great-grandmother.
Nicknames for grandmothers and great-grandmothers are often based on names that children make up themselves, or variations of the word "grandma," that are more easily pronounced by young children. Some grandmothers feel the nickname "grandma" makes them sound older than they feel, so they choose a different name.
Choose a traditional nickname for a great-grandma, such as Mammy, Gammy, Mimsy or Nonna, or a more trendy one, such as Coco, Bella, GG, Neema or Pippa. Choose a nickname with international flair, such as the German Oma, the Polish Busha, the Flemish Bomma or the Arabic Teta. Hawaiian grandmother nicknames are Puna, TuTu or Kuku. A Thai grandmother is called Ya.
Take inspiration from the nicknames of celebrity grandmothers. Goldie Hawn's grandchild calls hers "Glamma." Actress Blythe Danner's grandchildren prefer Lalo. Other playful great-grandmother nicknames include Booma, Bunny, GoMa, Lula and Nooni. Lovey, Sunny, Tootsie, Cookie and GoGo are other playful choices.
Many families differentiate between grandmother and great-grandmothers by adding a first name after the name "Grandma." If no other nickname resonates with a great-grandma named Mary, for example, use Grandma Mary.
