What do you call your in-laws?

[Glacier]

I call my father-in-law by his first name. I have never met my mother-in-law; she is unaware of my exsistance, so never had to deal with that issue!

Jerry & Cindy. When talking to Josh about them, I usually say "your mother/mom, your father/dad". When talking to Aidan about them, I'll say "your grandmother" (can't bring myself to call her what she wants to be called) and Josh's dad is "Pappy" to Aidan.

I call them by their names.... We don't see them too often (maybe once or twice a year) and I don't talk to them on the phone that often either (maybe five times a year) so it's not too often I talk to them.

My husband calls my parents by their names as well

I am very close to Mark's parents, probably closer than my own parents. I was especially close to Mark's Mom, and always called her "Mom". As far as Dad goes, I sometimes call him "Grandpa" too, because well, he seems to ba typical one.

Mom and Dad for my inlaws.
My FIL has passed away, I refer to him as "Dad" when speaking with hubby or my MIL.

My hubby doesnt talk to my mom that often on the phone.
He refers to her as "your mom" in conversations between two of us.

Ask them what names they would like you to use.

I call mine by their first names, but when the baby gets here, I will probably refer to them as Grandmama and Granddaddy just as often as I will use their names.

I call my in-laws by their first names, it took me a few years to do so, but once I did I felt MUCH more comfortable then calling them Mr. & Mrs.
It also helps that we go out with them once in a while to bars and stuff, so at times they are more like friends.
As for my hubby, he still calls my parents Mr. & Mrs. even though we've been together for 13 years! He just can't bring himself to call them by their first names. They keep telling him to call them by their first names, but he just still can't do it!!
