After “I Do”: What Do You Call Your Mother in Law?

What do you call your mother in law? Is it the same thing you called her before you were married, or did you make a switch?

Before we were married I avoided calling my MIL anything because I wasn’t sure what to call her. I would just stare in her general direction and hope that she would look up so that we could talk. Mature, I know. 🙂 But, now that we are married (and even before we were married if my stare trick didn’t work) I call her by her first name. It’s how she introduced herself to me, and avoiding calling her anything (especially when I need to call her on the phone) just doesn’t work.

I call her by her first name, which is the same thing that I called her before we were married.

I call my MIL by her first name. The first time I met her when Mr. FF and I were dating, I referenced her as “Mrs. LastName,” and she quickly asked for me to call her by her first name only. Easy peasy for me!

In the beginning, I called her “Mrs. ——.” As we grew to know each other, I just called her by her first name, and still do after our wedding. Mr. D calls my parents by their first names too. The whole calling in-laws “mom” and “dad” is a weird thing for me.

Joan.  Always have!

I’m also in the first name camp. Though, for his dad, I call him Papa T. He gets a kick out of it!

Ohhh my gosh. This is embarrassing. Before we were married, I called her “Mrs. XYZ.” And now? Come to think of it…in the past YEAR I have been at my in laws’ house for Sunday lunches almost every week, but I have never once used her name! What?!?! I guess if it came down to it, I’d use her first name…but it feels WEIRD to think about that.

I’m a first namer too. I asked Lambster what I should call her when we were dating and that’s what I’ve called her since. I figured she’d correct me if she wanted something else. 🙂

I have 2 MILs (I know, lucky me): a step-MIL and Mr Frenchie’s Mom. I call them both by their first name. No-one ever said please call me this, like my parents did for Mr Frenchie, so I just went with first names and figured they could correct me if they wanted. In the case of my step-MIL, Mr Frenchie calls her by her first name, so that was easy. However, with my MIL, Mr Frenchie obviously calls her mom and everyone else calls her by her nickname, Sue. I do still feel a little odd calling her Sue instead of Susan, but I usually just go with what I’m feeling at the time or just use the look directly at her and start taking method.

I call her by her first name, which is what I did before we were married (or the just start talking method which seems to be popular with others!). She usually signs emails and things with “Mom First Initial” which I think is sweet, but I don’t think I’d be comfortable just calling her mom all the time (that’s what I call my mom!).

I’ve always called my mother-in-law by her first name, and continued to do so after the wedding. She’s not my mom; she’s Linda, and so that’s what I call her.

I’ve always called her by her first name. Well, to be more respectful, I always say Ms. -first name-. Calling her mom never crossed my mind, because my mom is my only mom. 🙂

I call her by her first name. Always have, always will. The thought of calling anyone besides my own mom “mom” just weirds me out. Not for me!

In my family, EVERYONE calls their in laws mom and dad. Growing up, this never seemed strange to me. Is this a Pittsburgh thing? An Italian thing? Who knows. After getting engaged, however, I started thinking about it, and I realized that I couldn’t call someone mom or dad who weren’t my parents. Burger’s family calls in laws by first name, so it had never occurred to him to call my parents mom or dad.

Prior to getting married, we called each others’ parents Mr./Mrs. ____, and now we call them by first name. I think my mom would LOVE for Burger to call her mom, but my siblings and I call her by her nickname a lot anyway. Interestingly though, Burger and I both call each others’ extended family members aunt/uncle/grandma/grandpa! I think it’s because it seems too informal to call them by first name. 🙂

For the first few years, I avoided calling my MIL anything at all. Eventually, I became comfortable enough to use first names with my in-laws, which is what I still do, and Mr. HC for my parents. However, we are still working out how to write joint mail/cards. If I’m writing to my parents, no problem, I write “mom” or “dad” and sign both our names. But if it is for my in-laws, I have Mr. HC write it and sign our names—I feel funny calling them “mom” and “dad” because I would never do that in real life!

Count me in the “nothing” camp. Mr T’s parents never expressed their wishes or introduced themselves to me in a certain way. It seems too informal to call 70-somethings (at least non-American ones) by their first name, and they’re definitely not the “mom and dad” type.

Which is all to say—thank heavens for having a kid! It opens up a whole new world to the “nothing” camp once you can refer to your in-laws as grandma and grandpa (or amah and akong, in our case).

I call her by her first name in person, usually, or “MIL” in email or Facebook. If I’m feeling playful, I address her as Mom or Nana, but only in pretty specific contexts.

I’m her third kid-in-law, so my SILs set the tone before I came around; things might have been different if they hadn’t.

Hahaha, I’m just like FroYo, Buttons, Hermit Crab and Tulip. I’ll be all “hey…you” while looking at her. Or talk loudly in her general direction. I have called her by her first name, and I believe that’s what she’d be fine with…but it just seems odd for me to do it. Ditto with my FIL. So really, I just look at them and talk if possible. But if I need to get their attention, I’ll call our their first names.

I’m like quite a few of the others too: I kinda avoid calling her anything…bad daughter-in-law. She signs all her emails and cards with “Mom” and her other daughter-in-law calles her that, but I just can’t. It’s too weird for me. At the moment we live halfway around the world from my in-laws, so I can stick with this method of not calling her anything for awhile, but I know I will have eventually call her something. 😛 Maybe I will just pop out a grandchild for them so I can call her Grandma. Ha. I would prefer to call her by her first name, which is what Mr E uses for my parents, but I’m not sure if they approve of that. It is a little hard to tell. Ah well, that is a problem for Future Mrs Earrings to handle!

Zeb comes from a formal family. I addressed my friends parents by their first names but Zeb always did the Mr. & Mrs. Last Name thing. I was introduced to his parents as Mr. and Mrs. Last Name. (Zeb shares the same first name as his father.) I always addressed his parents as Mr. & Mrs until I began working with his mother when she asked me to call her by her first name. I still don’t know what to call his father because it is awkward for me to call him and Zeb the same name. (Most of Zeb’s family calls him by his middle name—it gets confusing.) I continued calling him Mr. until a few months ago when I started calling him Papa Zeb jokingly. It’s stuck and it works, so I’m sticking with it.

Funny story: after many awkward months of not knowing if I should go FirstName or Mrs. LastName Mr. Seashell’s Mom called me on the phone. I thought to myself, “Perfect! She’ll say who’s on the phone and I’ll know how to address her.” Not so much.


<It’s Mr. Seashell’s Mom! Hi!>

Ugh. Problem not solved. Weeks later I teased her and said she ruined my opportunity of knowing what to call her. We later settled on FirstName.

    I can SOOO relate! My now husband introduced me to his mother by her first name so that is what I call her. She signs cards from Mom so I think she’d like me to call her that but like you I cannot bring myself to do so. We are not close and I have stepparents whom I am very close to and I also call them by first name.
    You’re not alone!

    ugh my MIL asked me to call her mom.
    While we get along perfectly fine, I already have a mom and it’s my mom, not her. Now I just avoid saying a name for her.

    I call his mom “Lady” most of the time. She gets a kick out of it.

    I’m in the ‘nothing’ group. While my relationship with my parents is much closer, the FI’s parents don’t get involved in our relationship and while we get together with them more than my parents, they just keep to themselves and aren’t super affectionate. My mom is pretty judgmental and hasn’t been incredibly welcoming to the FI (no one will ever be good enough for this adopted, only child). The FI has always just thrown his arms around her, given her hugs and calls her “Mama Sue”, even when she’s been a pill. Hahaha. Awesome! And I think it worked. On his birthday she gave him a card and signed it “Mama Sue & Dad Mike”.

    BTW – If I HAVE to call the FMIL a name, it’s first name. Ug. So difficult! Just tell me what you’d prefer! 🙂

    Ugh I was SO happy to read these responses!! I feel so much less alone now!!!

    My mother raised me by herself from the time I was 2 – hence I don’t really feel all that comfortable calling anyone else that title.
    At our wedding, literally during the first 10 minutes of the reception, my MIL came over to me and said, “Well, it’s time to start calling me ‘mom’ now!” with a big grin on her face…

    I absolutely didn’t want to hurt her feelings – but I explained that for right now that’s not the most comfortable thing for me to call her (that might NEVER be the most comfortable thing for me to call her). I love her and I respect her as a mother, but she is not my mom and I can’t be pushed to call her otherwise. First names need to be ok for right now (although she still signs everything “Mom His-Last-Initial”).

    I suppose this is maybe made more complicated by the fact that he has no problem calling my mom “mom.” I also kept my last name, which I believe his family saw as a slight to begin with.

    I’m glad to know others are in the same “first name boat” that I am….

    I have a really different situation! My fiancee John called his parents by their first name. I was REALLY uncomfortable doing that as I called everyone Mrs. and Mrs. so and so. It felt really disrespectful to be to call them that but Mr. and Mrs. felt awkward. Somehow I came up with Ma and Pa (I call my parents Mum, Dad and Dad-my step-dad raised me). They look after their great nephew as well so this solved the issue of what he would call them. In fact it has stuck so much that even John calls them Ma and Pa now. 😀
    It is a lot more awkward with John and my parents. He sometimes calls my Mum, mum, mainly when on the phone but he always refers to my Dad as Peter. My parents are decades younger than his parents though so it makes sense for him to call them by their first names. We are headed over to stay with my parents in Australia next week so I guess we can talk about it then and see!

    Might be just a cultural thing. Here in Hawaii a majority of us call our in-laws “mom” and “dad” 🙂

    I call my MIL mum because I never really had a mother who cared about me and my MIL fills that gap.

    I always called my inlaws mom and dad. I took my queue from my own parents who called their mother in laws mom. Depends on the type of relationship you have with them I suppose. Nobody takes the place of my mom and dad and calling my inlaws mom and dad won’t ever change that. I think it just shows respect and closeness.

    I think what you call your “mom-in-law” reflects how you would like to be treated. If you want to be treated like a daughter, call her Mom. If you want to be treated like the wife of her son, call her by her first name. It is what you make it girls. 🙂
