Am I over thinking this?

[Wingingiteveryda]

My mother in law watches my son a day a week. He's two years old and very chatty. He's recently started calling our house "daddy's house" I didn't think much of it until I heard my mother in law refer to our marital home as "daddies house" to him when we were travelling home recently (without my partner) and again at a family party whilst speaking to family.
I mentioned this to my partner and he doesn't see the big deal but if I'm honest it's not sitting well with me. To me it sounds like our son lives with his dad rather than with his family. Not that it actually matters but our house is jointly owned by the pair of us and we worked very hard to get our deposit together a couple years ago.
Would I be unreasonable to ask that this stop and they simply refer to our house as my son's home? Or am I being oversensitive and overreacting?

And yes it was ‘our exp’s house’

Thanks everyone
There's not really much of a back story. She's always been quite difficult to get along with. I think the reason it gets my back up so much is that it has been said in front of me, both when my partner is and isn't there. We don't see my parents very often on account that we live at the other end of the country from them so I guess there isn't the opportunity for them to call our house "mummies house" (though I imagine they wouldn't say anything other than 'home')
We've been together almost 10 years and there's been a few boundary issues over the years with my mother in law (letting herself into the house when we're not expecting her/changing my sons routine without telling us/ taking away sons comforter because she disliked it to mention a couple) but I feel like I choose to raise only really problematic things with her as she hates to be questioned in anyway, but this is just really bugging me.
I'll speak it through with my partner this eve again, see if we can get around this without it becoming blown out of proportion. I'm also 6 months pregnant so need to make sure it's not just hormonal rage

YABU I always say - grans house, uncle XX house, Nanny XX house. It would be ridiculous to list all of the house members. Sometimes I say mummy and daddy’s house if I’m talking to little ones but if I just say mummies house I’m not doing it intentionally to leave the dad out or vice versa.

Do you work? Is she implying only her ds pays for things?

It would rile me up tbh. My MIL always talks about 'DH's house. Always. I've never pulled her up because I just can't be bothered, I think it riles me more because technically our house is in my name. I bought it myself before we married, and DH had his own flat. But if course that still just DH's flat.

I do think it if she's tlking to your DS then it makes more sense to say 'your house'

@30degreesandmeltinghere I work full time, as does my partner

My kids use granny as a verb for granny and grandad, like a package deal of 2 for 1.

Funny I call mum and dads house, mums house 🤷‍♀️

Your son will correct her soon enough little kids like things to be 100% correct.

@toocold54 I completely understand what you mean. I'm just finding that it's touching a nerve with me. They never spoke about our house as being my partners before my son arrived, it was always spoken about as going back to and 's, not just my partners home. I don't know why that would have changed
But you're probably right that I'm being over sensitive x

It’s strange as if I was speaking to a toddler about their home, where they lived with both parents I would just simply call it “home”. For example “you are going home now” or “you are going home to your own house”.

I wouldn’t call it mummy or daddies house, or mummy and daddies house. It’s his house too.

@harverina exactly my thoughts too, it's just his home. I understand people saying nanny's house/aunties house etc because they're places he visits, home is just home x

I honestly wouldn’t care.

LO sometimes calls home mammys house which I find hilarious and I poke fun at OH. Other days it’s daddy’s house. 🤷🏼‍♀️ I just call it home, and so will your LO eventually

I always call my DM and DF's house my mums house, and I call my MIL's house her house and when my children were little they called mine and DH's house 'mummies house' and my MIL called it 'Daddies house'. Now they are both older they call it home.

I think you’re over thinking it a bit OP, however I think it’s strange to be talking about mummy’s or daddy’s house tbh, would it not be more normal to say [insert little boy’s name]’s house, if talking to her grandson?

This would bug me and it is technically my husband’s home that he owned before we met
There’s just no need to say anything other then ‘home’. Feels like a dig.
