*please note that this question was solved in early october. We decided to let the grandparents choose. Another poster has a similar question further on on the thread, which is why it has resurrected.
For those interested my original post is still below.*
Is it ok for us as parents to choose what our DS will call his grandparents?
Here is some background:
He has one grandfather and two grandmothers.
He is the first grandchild in both families.
None of them live near us so DS will not see them very often.
after the birth of DS both sets of grandparents came to visit, both sets telling us what they want to be called. They want Pa, nanna and nannie.
My DP and I want to call them Grandpa, Grandma 'insert first name' and Grandma 'insert first name'.
so, can we as parents change it to suit ourselves?
