How to deal with older children who argue constantly?

[Troika]

They are 12 (dd) and nearly 11(ds) and are permanently at each other’s throats.

The screaming, the shouting, the shoving, the muuuuuum he/she did this

They actually seem to hate each other.

Any tips on how to deal with it?

No tips but a hand hold my two are the same

I don't tend to intervene immediately because the younger child had only just started challenging his sister! (13 & 10). However when it starts to become unreasonable ie nasty I tell them to stop.

It's draining I admit!?!

I no longer allow physical actions between them because I think they will hurt each other

I used tosend them to their rooms the pair of them didn't take sides or intervene unless I had too. As soon as i heard muuum tell her I would just send them away.

OMG, mine were like this. I feel for you, it is exhausting. I just heavily supervised mine and as soon as anything started getting fraught, I intervened immediately. Now I have managed to find space for them both on two different floors of the house so they're not in each other's faces.

A year down the line, they get on just fine! The year has made such a difference as they have both seem to have found their own space in life, with their own friends and interests. And then last night, the eldest one invited the youngest one out with his mates to play football. That warmed my cockles. Hang on in there!!

Oh I remember that stage - my two were terrible! Mainly younger (by 17 months) DS taunting DD who would then start throwing punches
We had to physically separate them sometimes when we hadn’t intervened in time before the fisticuffs started

They grew out of it and around 15/16 they mainly ignored each other.

They are now 20 and 19 and have a pretty good sibling relationship (even tho they are very different people)

Mine are in their 20s and get on great now.

Thank you everyone, it’s good to hear it may not last forever!

2yo dd2 has started shouting at us all too so yesterday I hit peak annoyance with it and told the older two that if they couldn’t speak nicely to each other then they could spend all their time at home apart from mealtimes sat in their own bedrooms with the doors closed because I am sick of all the shouting. Said that if they are going to continue making family time unpleasant for all of us with their arguing then they’d be excluded from it 😳 Probably not the best parenting in the world!

This is worse for ds tbh because he hates being on his own whereas dd is quite happy sat in her room drawing or reading but then again he is the more argumentative and aggressive of the two anyway...

one upstairs, and one downstairs.
i have 2 siblings and our parents would immediately separate us at the first sign of it kicking off.
in our case it was one upstairs, one downstairs, and one in the outside converted coal shed, it was snug in there.

I don't know.
Last week I had a semi-serious huff and said they weren't allowed to talk or interact with each other in the house. It's unbearable.

I take them out a lot to keep the peace.
