Parents-in-Law. What do/did you call them?

By their first names.
Same as sons in Law call us by ours.

Until we were actually married I had to call my OH parents
Mr xxx and Mrs xxx. It was only after the wedding that I was allowed to call them mum and dad. I soon discovered that I had migrated into a very strange, regimented family where females 'had to know their place' with a pecking or dilated by age and immediate/non immediate family. Not a particularly happy part of my existence.

First names. Each to their own, but I personally wouldn't want to address a spouse's parents as "mum and dad" simply because they aren't/weren't my mum or dad. Our children's other halves, always calls us by our first names and when we send Christmas cards we sign it mum and dad and underneath that our first names. Birthday cards to partners we sign our first names.

The French address their parents in law as belle-mere and beau pere, how bizarre! so glad I didn't know that when I had a French father in law, first marriage, he wouldn't have been my beau pere no way! neither would my English late father in law come to that, more like "douleur dans le derriere" Mothers in law were both nice so could possibly have entered the belle mere category.

My in-laws insisted on being called by their first names, but it never felt natural to me. My husband certainly didn’t:call my parents by their first names. - they would’t have liked that. I think he avoided calling them anything.

Yes come to think of it, reading others posts, I don't think I called them anything either, maybe once or twice when necessary, it would have been first names.

Septimia

Mam and Dad.
Happy for our DiL to use our Christian names. Don't mind if adult nieces and nephews drop the "Auntie" and "Uncle" - they know the relationship after all.

DIL and SIL use our first names.
I told nieces and nephews to drop the Aunty and Uncle, some have, some not.

I avoided calling my in laws anything until they became nan and pop (their choice). Our children’s partners call us by our first names.

Evil

My MIL said she’d decide what I should call her once I was married. I avoided calling her anything until Nan was appropriate. FIL said to call him by his nickname like everyone else did. DH referred to my parents as Mum and Dad.
One SIL calls me Madre, the other by my first name.

My 3 SiL call me Marmight - not really but you know what I mean 🤣 (probably something else behind my back!) and my 3 DDs use their in-laws first names. Much easier for all concerned. Thinking about it after reading all the posts, I may have referred to my in-laws as Grandma/Grandpa once the girls were born. Sooo long ago now. Life was much more formal in our parent’s & grandparent’s day.

First names for my in-laws and DH does the same. Our AC's partners call us by our first names too.
It only gets tricky when signing a card - wedding anniversary for each of them usually - and then I sign mum/name which always feels rather clumsy.

I don’t call them anything, like some others I mumbled something if needed, but as we didn’t see them very often the situation never really arose.
MrOops called my parents by their first names.

First names.

First names. Never occurred to do otherwise.

My mum died 10 years ago. My MIL has said a few times, 'Call me mum since you don't have one anymore'.

I know she means well but it doesn't feel right to me. I am in my 60's and she is in her 80's anyway.

I generally don't call her anything but if I need to it is usually her first name.

Mr C’s dad had died before we met. I now feel very ashamed I didn’t use a name when speaking to his Mum. 18 when we met she was in her 60’s and seemed more like a grandparent. An incredibly capable woman I was in awe of her although she was always welcoming. Distance meant I spent little time in her company. Once our children came along she became Nan C. When both his parents had died Mr C slipped into calling my parents Mum and Dad. I’ve no idea what they thought. They never commented. Our daughters in law call us by our first names and seem comfortable doing so. We’re very happy with their choices.

Christian names.

By their Christian names. They were not my mum and dad.

I called them by their first names.

My MIL was called Maman as she was Belgian, and my FIL we called Pops..

MIL is called a cute variation of gran, a name that my boys called her when they were little, and FIL is a very silly triple barrelled hyphenated name the boys gave him!

If I talk to someone outside the family about them then I use their first names.

First names

Nothing until the children arrived, then Gran and Grandpa.

First names, always. My AC's partners use our first names too - I wouldn't want anything else.
