AIBU to stop making the effort with uninvolved sister-in-law?

Am I being unreasonable to not want a relationship with sister in law due to her lack of effort and contact with my children (her niece and nephew).

Sister and law and her partner are much older than myself and partner, they in their late forties / early fifties. MIL had her very young. They don’t have their own children, they have been together 25 plus years but only moved in together about 10 years ago,
SIL lived with MIL until then.

When we had our daughter nearly 5 years ago and we made a huge effort to involve them, we made them god parents (I know that doesn’t mean much these days, but we wanted to give them that honour). They were somewhat involved with my daughter and we would see them maybe every month at one point, at either ours or theirs, but as time went on the contact got less and less.

We had our son nearly two years ago and they have seen him probably 4 times his whole life. One of which was at his christening, then we went to visit them last Christmas and we saw them at MILs last week, wasn’t planned but they turned up when we were there. The other time was when they visited our house when he was born.

She doesn’t call or text to ask how the children are, she doesn’t invite us round or ask if she can visit us. I’m just done with it to be honest, I don’t see why we should make all the effort when she clearly couldn’t care less. Whenever she does see them, she takes a tonne of photos and posts them on social media- that really annoys me and I have commented and asked that she doesn’t upload our children onto social media as we don’t agree with it.

MIL has contacted my partner today and told him that he must talk to his sister more and check in on her and make sure she is okay. Why don’t we see her etc etc. he told MIL it is not his responsibility to make sure she is ok and that she knows where we live too. (I would like to add MIL is a whole other story and nightmare herself, but that isn’t the point of this post of course)

But anyway, AIBU to be pissed off and to say actually I don’t want anything to do with her anymore? Or am I being harsh and should I make more of an effort to try and involve her?

OP my family take an interest and help each other out. Even so, you sound like a lot.

Could she honestly have declined being godparent? If you think it's an honour, I imagine you would have been mightily insulted if she'd said no thanks.

Do you know she is "moaning" (horrible term) about not seeing you? Or is this just something your mother in law says?

You sound a bit like my sister in law. She is a nice enough woman but quite obsessed with her children and very oblivious. She makes lot of quite rude comments without even realising - like you, with your slighting comments about their empty lives. She doesn't mean any harm but her own world is restricted to her children and she will make judgy little asides about women who have "careers" or use IVF or go back to work. She is not a bad person, but quite hard work socially. I think she thinks of herself as a reasonable, nice person and probably has no idea how she comes across outside her own circle.

EmotionalBlackmail · 18/07/2026 15:06

Does your MIL perhaps know something is wrong with your SIL and is encouraging your DH to offer her support?

It sounds like a very one-sided relationship where you’re expecting a lot of input and interaction for your children from your SIL but what’s she getting from the relationship? You’re rude about her lifestyle. How much did you see them before you had your children?

I reduced contact with my relatives and nephews/nieces after it became apparent they were only interested in my interactions with their children. They couldn’t be bothered to take an interest in my job, social life, pressures I’m under etc?

TheIdlerReturns · 18/07/2026 11:51

Kindly, I think you don't want to listen to opinions here which are on the whole saying the same thing. I think you just want to follow your own narrative because you don't agree with what people are saying. Why come on here? No-one has to be interested in you or your children, family or not, but I don't think you want to hear that.

Whatthefork1 · 18/07/2026 11:37

TheIdlerReturns · 18/07/2026 10:57

All the more reason not to be that interested in your DC. I don't understand why you feel like this. She's got her own life.

I don’t think because she’s his half sister is reason to not be interested. They never refer to eachother as half siblings and they both lived together with their mum until DH was about 23.

Whatthefork1 · 16/07/2026 17:13

Yes she is and no becuase they are not sisters, both are DH’s half sisters, so the two sisters are not related.

All the more reason not to be that interested in your DC. I don't understand why you feel like this. She's got her own life.

Why do people suddenly turn very insular when they have children, no one needs to be involved in your children only their parents

I am perfectly capable of having adult relationships and connections with people as they are it is a great skill for a grown up to have

@PollyBell It sounds as if the OP's DH and his sister are very different people and they're not particularly interested in each other's lives, let alone each other's partners and children. It's fine, families aren't always close.

EssCarGo · 17/07/2026 23:20

I never get these threads!

My SIL isn’t interested in seeing me much so I will punish her by making it NEVER.

Makes no sense!

Beingseenisneedy · 17/07/2026 22:45

You can still have a relationship with her, even if she's not into your kids.
As long as she doesn't hate them or is abusive, there's no reason to fall out.

I love kids, but also have a stressful job, so when I have free time, the last thing on my mind is to call DB and DSIL about the nephews.

When I see them, we have a lovely time, until next time.

My DSis does video call the nephews, which she enjoys.

I couldn't bear it honestly as I like quiet boring time.
No one is wrong, it's because we're all different.

Just match her energy OP.
Do what she does.
Evens.

Tableforjoan · 17/07/2026 18:42

Yes honestly most people although nice in person only really care truly about their own children and then grandchildren.

They may be fond of others children but mostly that comes down to the relationship the adults have with each other.

If my best friend had a baby then I’d be excited and couldn’t wait for a cuddle and be asking her loads of stuff and buying lots of little bits.

But my sil well she’s my sil and she’s dh’s problem. We are not friends we are just in-laws who are polite and friendly in person because we both love my dh basically. If we divorced I’d never see her or her children again.

I don’t consider them my nieces or nephews although I don’t verbalise that either they are dh’s nieces and nephews. I don’t hate them but I don’t love them. My world wouldn’t stop if I never saw them or heard about them again. I’d be sad if something happened to them the same way it would be sad that anything happened to any child but there is no bond and life would go on.

Coralsunset · 17/07/2026 18:31

Oh bless you OP. No, the vast majority of people don’t really give a shite about your DC. They say nice things to be polite.

You have been naive but there’s no reason to fall out with SIL just because she’s not crazy about your child.

KaleidoscopeSmile · 17/07/2026 12:06

we made them god parents (I know that doesn’t mean much these days, but we wanted to give them that honour)

It’s not that she SHOULD be [more involved with OP's family], it’s more a question of - why wouldn’t she want to be? I just simply don’t get it.

I can't decide if you're a card OP or just have main character energy on behalf of your entire little faaaaahmily

I’ve certainly not got main character energy, I’m quite the opposite of that in terms of personality.

I think, after reading all of the comments I am just naive in thinking that everyone (family) loves and thinks my kids are great as much as I do and a lot of our family do, which is lovely, but I realise that can’t be true for all.

ClovisWrites · 17/07/2026 09:07

Maybe you and your DH aren't her cup of tea. That's okay, isn't it?

LittleMonks11 · 17/07/2026 09:00

Just leave the woman alone and stop mithering about her.

nam3c4ang3 · 17/07/2026 08:59

Christ - stop being so self centred OP - she hasn't had kids, maybe it was a choice and she doesnt find them interesting OR she tried to have them and failed - can you really not see that there might be reasons why? Not everyone finds your kids interesting you know....prob just you and your husband,..just leave them be, i dont know why you want to cut her off from your life - she hasnt done anything.

user1492757084 · 17/07/2026 08:56

Every one's best is different. Give your SIL unconditional love.
Treat all SIL with the same respect, Op.

You don't need to see her too often but do not show your children how to be mean. They are older relatives and boring ... but have self respect and be kind.

You husband could take one child over to see them every month.

Well shit, guess I'm a crappy aunt 😁

Well I definitely am. I know more about 2 niece)nephews now they are adults and speak to me occasionally on Facebook but the younger one I've seen twice in her life ( she's nearly 10) both of them at my mums house when they happened to be there

Nothing wrong with any of the kids but I don't see why I would have any real interest in tgen

Thechaseison71 · 17/07/2026 08:50

I'm confused Why exactly are you expecting them to be asking after your kids? And visiting you etc?

Netcurtainnelly · 17/07/2026 08:48

Your hearts in the right place OP but being family doesn't guarantee people will be interested. I think if it's not there naturally, you can't force it.

minimalistic · 17/07/2026 08:28

@Whatthefork1 I had a very similar situation when my DC were little. I couldn’t fathom the lack of interest from in-laws, esp SIL. It was upsetting tbh as we really could have done with the ‘village’. But what goes around, comes around. SIL has a little one now and I’m now delighted to not owe her anything. We NEVER have to babysit or help in general. We have a cushty time with older DC who generally look after themselves.

I’m pretty sure SIL has no idea why we don’t bother. She’s far too selfish to consider her own previous behaviour.

Todayismyfavouriteday · 17/07/2026 01:12

People who choose not to have children are rarely interested in being closely involved with other people's children, whether they are family or not. I wasn't, until I had my own. By then, I'd fallen out with my sister-in-law, who claimed I did not pay enough attention to my niece - which was true, but that's the way I felt at the time. You can't force your children on other people; not even family. Just let them be.

BruFord · 16/07/2026 21:11

LakieLady · 16/07/2026 18:22

Some people just find small children hard work, OP. I'm one of them, which is why I'm childfree by choice. I found them much harder as I got older and, tbh, I don't find them very interesting.

Once they're into double figures, it's a whole different matter. I find older children and (especially) teenagers much more interesting and engaging. I'm the favourite aunty of a couple of my nieces and was the person they trusted and would tell things to that they didn't want to tell their parents. There were at least 2 occasions when I supported them to tell their parents stuff they would otherwise have been afraid to disclose. I'm closer to them now they're in their 20s and 30s than I ever was when they were under 12 or so. Your SIL may be similar.

And you're being very judgey to describe her life as "just existing". For all you know, she may be someone who likes a quiet life and is perfectly happy chilling at home.

Edited

@LakieLady I think that's part of the OP's issue tbh. The idea that her SIL might pick and choose when to be part of their lives, i.e., they're too much work now, but perhaps they'll be acceptable to her when they're older! It's the reverse of dropping a previously energetic and engaging relative when they become elderly and unwell.

BruFord · 16/07/2026 21:01

Focus on the people who are interested in you/your family and if your DH wants to reach out more to his sister (and vice versa), he will.
