I am Grandma to my three grandchildren and will be the same to my Great Grandson when he can get his tongue round it. Decided to stay the same to him as he has both sets of grandparents and both sets of great grandparents. In fact he has three sets of great grandparents as one set divorced and both married again. OH is called grandad the same as with the grandchildren and great grandson can say that without any trouble. Other great grandmother says she wants him to call her G.G for great grandmother. My daughter titters every time she says it. She thinks she sounds like a porn star.
