when i first started dating my hubby ( 6 years ago), i called them by their names ( Becky and Glen). then for a while they hated me ( like every parent of a soo good looking man does ) then recently i have been using whatever i feel most comfortable. My hubby's mom is getting use to talking to me know, LMAO, in fact this last week she told her son that she wanted to talk to me about sending her something. LOL .. she said she did not trust her son to send her the important documents that she needed for his taxes. LOL, that made me feel good as well.

it took along time for them to feel comfortable around me and my son. she does accept Brady as her grandson now. but, as for me, it took more time.

i think it all depends on who the person is. like their personality, and upbringing. Jeremy's dad Glen is very business like and loves to us Full names and all the uptight stuff. whereas Becky, ( his mom) is more like the get it done type of person, she likes to use names but, more like nicknames.

either way, i think you will be fine calling them grammy and grandad
