If your children have half or step siblings do you correct them when they say “brother/sister” so they use the proper term?

YABU - yes I do
YANBU - no I do not

My Dd has a half brother 32 years hr senior, from the minute we knew he called her 'sister' he made it quite clear she was his sister, not half sister. Whem Dd was small.she used to call.him.'my brother called (name) ' they still say brother and sister 22 years on. Ask the children see what they say

Ladyingreen999 · 21/02/2025 18:12

It looks like you asked the question the wrong way around, asking people who do correct their children, same as you do apparently, to vote "you are being unreasonable". It should be the other way around. Maybe thats why you think 13% people agree with you when they simply clicked "unreasonable" after reading your post.

What is the likelihood of growing up in the same house though? It's an odd dynamic for children to not share the same parents, IDC what anyone says.
'Ok mum, and Sally, I'm off to my dads for 5 days now' While Sally stays in her home with her parents. It's dysfunctional. I knew I'd get a lot of flak for my comments but it is my lived experience and that is how it was.

After my exh and I split up, both children went to their dad's together. There Is nearly 8 years between them. My son has been raised by his (step)dad since he was a baby.

They're incredibly close and far closer than me and my (full) brother. They're 27 and 18 now. They're in contact every day, he visits her at university, they have a holiday booked together at Easter.

I think your imagination is filling in a fair few blanks here and isn't actually an accurate reflection of the lives people live or the relationships that exist.

It's not about getting flak for your comments - you're entitled to whatever opinion you like but your assumptions are just simply wrong.

There is clearly a history here which I don't know!
But I think yabu. I was brought up in a blended family and refer to my half siblings as brothers and sisters. I would have been so hurt if my parents had corrected me and reminded me that I was the outlier who came from a different set of parents.
I mean you talk about having to explain to people but really noone takes that much notice and people come from all sorts of families so no one's judging you.

Ok but I don’t want them to say brother and sister in my house, they’ve been told and still continue to do it. Am I the “psychopath” for correcting them??

Yes, yes you are.

Perhaps think about why they might be doing this, instead of only thinking about this from your own point of view.

BobbyBiscuits · 21/02/2025 13:35

A half sibling is still a brother or sister. Step siblings, well it's up to them how they label eachother I suppose. I don't think anyone sensible would 'correct' someone on such things?

I’m a paediatric nurse and the number of times one of my kids says “I’ve got 10 siblings” and the mum says “well no you’ve got xyz at daddy’s house and xyz at my house. So I know I’m not the only one

That's probably just to curtail any judgement about having ten children, and because people think medical professionals might need to know exactly the family set up.

Why not though? Say for example mum has a 4 year old then a baby with someone else. Literally the children are " half" siblings but will grow up in the same house . What difference does the fact they have different biological father's make?

It’s weird to state that it would never be the same as fact, rather than opinion.

The 10 year age gap you have between you and your own half sibling is quite naturally going to be quite a big factor in how close you are or are not. This is true of full siblings with large age gaps too.

I have a few friends whose siblings are technically half. They’re very close, absolutely don’t refer to each other as half siblings. One observation would be that they all share the same mother, the closeness seems lesser though still present, when the siblings only share a father. Perhaps this is related to age and how typical custody arrangements were at the time. I’d guess with 50:50 custody being much more common, the difference between mothers/father children is less these days than it would have been, because upbringings are still being shared.

I never stated it was a fact. Of course it is my opinion.

'This is true of full siblings with large age gaps too.'
Not to the same extent. If parents are still together therefore equally invested in their shared biological child it doesn't create the same environment as blended families were stepparents are clearly not as bothered about their stepchildren as they are their own biological children.

I agree with your observations regarding custody etc. This is my point. If you have children that split their time between two households and one that doesn't because you are with the father/mother of that child, then it does create a feeling of inequality amongst the kids. Also, just the basic amount of time half/step siblings spend together as a result of shared custody means a lesser bond.

Princessconsuelabananahammock9 · 20/02/2025 15:13

You’re wrong though.

Half makes no difference for a lot of us. How can you say they will NEVER have as strong as a bond?

My sister and bother are my sister and brother. We all have different fathers and it makes us no less close.

Does the same go for adopted siblings?

But the half does makes a difference to a lot of us also. Me saying 'never' was perhaps a bit harsh but it is the circumstances that surround having half siblings that usually mean they are not as close as full siblings. And I will be honest, IME being fully related does create a deeper bond.

Yes, I think the same would go for adopted siblings if two were full siblings and the third was an adoptee. If all were adoptees it would be different.

TheBigFatMermaid · 21/02/2025 10:56

My child talks about their “brothers and sisters” often. They don’t have brothers and sisters. They have step brothers and half sisters. I’m sick of constantly having to correct them and then explain to other people the family dynamic because they are obviously confused. Several people agree with me as shown in my poll. They just haven’t spoken up yet.

I absolutely do not agree with you. When I was pregnant with my eldest DD, my then SDD would say happily that she was having a baby brother or sister. Then she started saying that the baby would "only" be her half brother or sister. I gently said that yes, they only shared a dad but one day the baby would have other siblings and if SDD wanted to choose to be the odd one out, that was up to her,but in my mind,none of them were "half a person". It was her Mum trying to diminish the relationship they would have and more harmful to SDD than anyone,I guess.

As it is, I did not have more DC with him, he left me and I had 2 more DC with my partner of 20 years.

My eldest DD doesn't have a relationship at all with her older sister but is very close to her younger siblings. My DP is very much an involved Grandparent to my eldest DDs children, has my eldest DDs name tattooed on his arm and I have been told by DD that if ever we split (not on the cards) she will not choose between us.

I think you will only cause upset by constantly correcting your DC on this. It is not about what you want or what is "factual", you are coming across as bitter and that is never positive.

As for being a MW and someone saying in front of you to their DC, obviously that was done to explain to you.

"It's hard when you're hurt" I get that.... think of it as a kindness you are doing for your DC and in the long term, for yourself. They will pick up on the bitterness and that will not be good for your relationship with them.

GertrudePerkinsPaperyThing · 21/02/2025 10:41

Blimey, how awful to correct children saying “brothers and sisters”.

I’ve skimmed the thread and can see it’s painful for you but this isn’t the way to go.

I always call my kids siblings just that - brothers and sisters - but they are technically half siblings from my exh.

Even if I’m explaining to others, if my dc are there I’ll say “dc have a brother and sister who aren’t my children/ who are their dad’s children” etc

I’d never say half!

It’s just hurtful to your own dc to say that.

marmaladeandpeanutbutter · 21/02/2025 10:37

God no, what an awful thought.

Jayne35 · 21/02/2025 10:34

I would not. I have half siblings and I never call them that, it's just brother/sister.

No im not still in love with him, I guess I never got the life I thought i deserve. We had a shit marriage and he seems so happy now and they have everything I ever wanted and I don’t understand why he wasn’t like that with me

Finally a bit of sense you really should let go of clear hatred for your child's sake and if your other thread is true you really need to be more flexible with letting child see her other family at weekends yes I know you don't like thought if them all happy together going somewhere nice at weekend but if he goes for 50/50 you will see your child less unfortunately your child has two parents not just you

OldLondonDad · 21/02/2025 09:39

Seems so weird that anyone would want their kids (step, half, whatever...) to use language that creates division and makes at least 1 feel less like they belong, than to use language that bonds them together and creates a sense of belonging?!?

(other than the pissed off ex etc.)

Surely having them literally see themselves as "all one big happy family" is a good thing?

GreyCarpet · 21/02/2025 09:20

However, parents who actively pretend like the half makes no difference do so for themselves. It is like they don't want to admit or accept that a child will never have as strong a bond with a half sibling as they would with their full sibling.

This just doesn't make any sense.

If both children are raised together from the youngest birth, as 'full' siblings would be, how would it have any bearing on their relationship?

It think depends on where they live, if they live together they bond as full siblings.
If they don't live together, its different.

I have a few friends that blended families,,

A friend with 3, the youngest, the half sibling, is very close to older siblings he lives with.
He isn't as close to Dad's first set of children.

It's all a bit messy, especially if they split and a 3rd/4th family are merged.

gettingthehangofsewing · 21/02/2025 02:03

My DDs have a half brother in our house, a half sister and a step sister in exdh second wife's house and a half brother and 3 step brothers in their dad's current house with third wife.

They refer to them all as brothers and sisters except the 3 step brothers as they met them as adults so do not feel a sibling relationship with them.

I wouldn't dream of correcting them as it's like implying the relationship is lesser. Obviously there may be times you need to clarify but a similar "they're his dads children" should suffice

neilyoungismyhero · 21/02/2025 01:20

The word step or half sibling has never ever been uttered in our house. They think of each other as full sisters and brother. Two from 1st marriage 1 from 2nd. No one even knows they have different fathers.

PepsiPepsiPepsi · 21/02/2025 01:17

I think it depends on the situation.. my kids have a half sibling on their fathers side who they've never met and they don't have contact with their father. I don't refer to this child as their sibling and neither do they but obviously that's a different situation to the op.

Step siblings should not be calling themselves anything but step siblings.

Half siblings are different. I don't think constantly pointing out or correcting children about one of them being a half is particularly kind. However, parents who actively pretend like the half makes no difference do so for themselves. It is like they don't want to admit or accept that a child will never have as strong a bond with a half sibling as they would with their full sibling.

Don't be ridiculous. Step siblings should refer to themselves and their step siblings however they choose. It's their relationship and their business. If someone was talking about their sibling, why would anyone need know that the sibling was actually a step sibling?
Of course a child can have as strong a bond with a half sibling as they can with a full sibling. The strength of sibling bonds depend on much more than the amount of DNA, if any is shared.

Bearhunt468 · 20/02/2025 19:06

Just seen your updates, you need to try and seek help or counselling. You don't want to push your child away because of your hurt. It's completely understandable how you feel but you absolutely need to try to heal yourself. ❤️

Pickledeverything · 20/02/2025 02:09

That’s just weird though. You’re not his child why would he do that what if your mum and him split up? He’d forever have some random kids name on his arm and have to explain that to his next partner

Sometimes even if you cant believe it or don't want to accept it but stepparents can genuinely love that child and be in their lives even if they got divorced. I know someone who calls they stepdad their dad even though the mum has been divorced from them for 20+ years because that man was the person who brought her up and was more of a father then her biological dad was.

You really need to stop enforcing your child to specifically say half sibling. They should be able to just say brother or sister if they want roo. My DH has two half siblings, they all just say brother or sisters and don't differentiate.
