I have six beautiful, bright grand daughters ranging from 10 - 1 years old (with two more to arrive shortly

) and as I prepare to tell the family of my upcoming transition I wondered what they should call me. I've always been Grandpa Jim and they already have three loving grandmothers. Can anyone share with me how they have handled a similar situation?
Thanks
Jamie
