My in-laws were already decided 19 years before my DS lol so MIL is Nunu and FIL is Pa. DS is my fathers first grandchild and he avoided answering my questions of what he wanted to be called....he had no name til my DS's first Xmas and he signed the card "love Grandad" so that was that!! I always wanted DS to have a "Nana" cos I remember mine as a child being such a warm cuddly loving woman.....so I asked stepMIL if she would like to be Nana or NanaPam, her response "just Pam is fine" huh ok!!! Makes me sad because my mother passed away many years ago and has no grandparent name and my MIL has recently passed.....so my DS has Grandad, Pa and "just Pam" hmmm
