I've been with my partner for 8 years and we have dc together, he has a son from his previous relationship. He's 15 and not his bio son but he's been in his life since he was young and he sees him as his dad

Alot happened when we got together as his ex would tell SS that DP didn't want to see him anymore now he was dating me which wasn't true at all. She was physically & verbally abusive towards him and he's been living with us since he was 13 (after he told school about howHe has a lot of trauma and anger which school are supportive about and outside of school he gets help on how to manage the anger and he is a lot better than he was but the anger is still there so we are just patient with him

We're currently on holiday with my sister and her 2 dc and have been here since Monday. There was issues almost straight away as ss got angry at the claw machine but he and dp left the arcade and went for a walk to calm down as the arcade was busy so there was no way he'd have been able to calm down whilst in the arcade. My sister described him as a tantrumming toddler who didn't get his own way and said partner wasn't doing him any favours. I ignored her

He loves drawing and usually if you ask he will show what he's drawing but earlier he was at the table drawing and my niece (10) kept asking what he was drawing. He told her but she kept saying “show me show me” despite him saying no, she pulled his sketch book away from him which caused him to shout at her and she “accidentally” spilt her water on it. He was clearly very angry/upset and walked off to go to his room and she followed him and called him a baby, asked if he was going to cry etc, and he turned round and hit her and now he's being made out to be the bad guy

During this my sister was out with her other dc, my dp was in the shower and I was telling her multiple times to leave him alone and do something else even when she was repeatedly telling him to show her his drawing and she ignored me

My sister is now back and furious, she said she doesn't want her children to share a space with a “violent man”, and has even mentioned going to the police and social services on us if we're happy to have him around our children as he's not related to us when asked where he should go she just replied care

AIBU to think she's overreacting? I know SS shouldn't have hit her and he knows this too but she hasn't apologised for her part in deliberatly winding him up and sister says she doesn't need to as she's a child and he's nearly an adult

At 15 if he has not gone through puberty yet you should take him to a doctor.

If he has gone through puberty then he absolutely is strong enough to hurt a ten year old girl. Even if he’s not much taller than her he will be much stronger than her.

If I was your sister I would be calling the police to have him arrested for assault.

Whatever help he is getting is not enough.

Netcurtainnelly · 13/08/2026 14:54

Sister should be supervising her own kid.

You aren’t wrong but where is the sister in all this. I would be very pissed off with my daughter and would absolutely be insisting she apologise for the nasty name calling and also ruining his drawing.

it’s incredibly sad actually for the boy and he is a boy, not a man.

The thing is though, it was an escalation of juvenile behaviour by both of them, not one single event.

She pestered to see his notebook for a while and eventually grabbed it..

He then shouted at her..

water was then spilled on it (assuming in the grapple).

He walked off

She called him a baby and asked if he was going to cry..

He hit her..

OP had plenty of time to step in and stop the pestering, and she should absolutely have stepped in as soon as SS started shouting at niece, he is prone to out of proportion anger and violence so any potential situation with other children should be de-escalated immediately, not left to chance, no matter who "started it".. as the person responsible for both children at the time this is 100% OPs fuckup.

AlwaysExtraHot · 13/08/2026 14:54

I agree with this. The sister needs to look at her parenting.

DurinsBane · 13/08/2026 14:53

How did he hit her? A punch in the face is different to a slap on the arm (though yes he shouldn’t do either)

Francine84 · 13/08/2026 14:53

You and your DH are in the wrong here. A 15 year old boy hitting a 10 year old is a massive concern and you’re minimising it again and again. His behaviour is unacceptable.

I wouldn’t want my children anywhere near yours until he learns not to be violent and aggressive.

Adossieronme · 13/08/2026 14:53

Imagine this boy at school
If / when his classmates ever wind him up

terrifying

Minasama · 13/08/2026 14:49

From the way you tell it, she sounds like she deserved a smack because she wouldn’t let it be and actively sabotaged his drawing and this will be a good lesson to her in future.
Nevertheless it does sound quite disturbing that a 15 yo would hit a 10 yo and if he has grown (rather than still being a small boy) that sounds even more upsetting.
Reporting to social services is ridiculous though. Both kids need a good talking to and to be separated.

She “deserved” a smack? From a 15 year old boy, when she’s… 10

JustSawJohnny · 13/08/2026 14:52

Adossieronme · 13/08/2026 14:39

The 10 year old behaved like an annoying little sister

The 15 year old behaved like a violent brute

The end

THIS. In SPADES!

JustSawJohnny · 13/08/2026 14:50

Naaah, if this is real it's a JOKE!

DNiece sounds annoying BUT SHE'S TEN!!!

He is fifteen, FFS!

A divorce and a temper is no excuse for him hitting a much younger child, especially a girl!

To say they were 'equally' in the wrong is an INSANE level of delusion!

I hope Dis does call the Police because she's right - he is being babied and his anger issues minimised to a worrying level and next time he hits out in temper he could either meet fists/.kicks himself or be of an age where he ends up in prison.

DH needs to do stop making excuses for DSS and give him a huge bollocking before it's too late.

Heronwatcher · 13/08/2026 14:49

No she is not overreacting. I have a huge amount of sympathy for your DSS but I would also have been absolutely livid if a 15 yr old boy had hit my DD when she was 10.

I think however much help your DSS is getting he’s not at the point when he can go on holiday with other children or be left unsupervised. Yes the 10 yr old was being annoying but… news flash… that’s what 10 yr olds do. You absolutely cannot allow a 15 yr old to hit them. I suspect your sister is a bit appalled that you’re not taking this more seriously too.

Personally I think you guys should go home- I don’t think you can recover this holiday. I wouldn’t go away with your DS or any other cousins/ children for the future. I’d also seriously review the support your DS is getting as frankly it doesn’t sound as though it’s working.

Balloonhearts · 13/08/2026 14:49

Six of one, half a dozen of the other. You should have physically intervened, as soon as it became physical, when she wrecked his sketch.

Feeding a baby isn't an excuse, how do you think parents of multiple children manage? I don't let the older ones run feral just because I'm feeding.

Put the baby down for a minute, yes they'll cry. Take her by the arm, remove her from the room, give her a good bollocking and send her to her room if she can't behave.

SunnyRedSnail · 13/08/2026 14:49

itsgettingweird · 13/08/2026 14:28

He shouldn’t have hit her.

but he knows that.

He used the strategies taught and walked away and she followed him and was taunting him.

If he hadn’t have hit her would she have followed him into his room? Around the resort? When would she have stopped?

I think anyone would have trouble not reacting physically to remove someone who is taunting them and a hormonal 15yo boy who doesn’t have any biological failing whir life will struggle more.

I think the holiday needs to end. Let your sister do what she wants as the authorities will look at the bigger picture and not just 15yo boy Vs 10yo girl.

Keep him in therapy and keep working on him learning strategies to cope because hitting isn't the answer and he may find himself trapped by someone following and taunting him again and he needs to be able to manage this.

100% this! ^^

Hitting someone isn't right, but hitting someone after being repeatedly antagonised is not the same as hitting someone for no reason whatsoever.

If the sister takes this to social services then her own parenting should and will come under question.

Where has her daughter learned that it's OK to deliberately do things to make someone angry, then keep doing nasty things even after that person has the common sense to walk away? Because that's a learned behaviour.

Why did the sister leave her daughter given she referred to the 15 year old as a "tantruming toddler" and knew he had anger issues? She must have known what her daughter was like so she shouldn't have left her.

The bottom line is that the ONLY reason this happened was down to the behaviour of the 10 year old. A 10 year old is legally responsible for their behaviour, so she knew full well what she was doing. She saw him get angry, she saw him walk away, but she made the choice to keep going and winding him up.

You just have to look up "mitigating circumstances" online to see how many sentences are thrown out due to the victim actually being the cause of the issue.

OlderGlaswegianLivingInDevon · 13/08/2026 14:49

The 15 year old male is old enough to be charged with assault.

You need to bear that in mind.

DecisionTime123 · 13/08/2026 14:48

There was a woman on here last week whose husband was being a dick to her, so she threw a cloth child's hat in his direction, it missed him and knocked over a plastic bottle and some water spilt on the floor. Huge number of posters saying she had abused him.

Yet apparently, if a 10 year old girl is being a brat, then she deserves a little slap eh? nothing wrong with that. She was asking for it ..

@Hadenough32 has clearly and calmly explained what should have happened. You need to do better OP. Unless you let your DH rough you up if you get a bit annoying?

Tableforjoan · 13/08/2026 14:47

10 year old acting like a annoying kid.

15 year own turned around and punched a 10 year old the 15 year old is the one more in the wrong.

If you can’t stop him hitting people you shouldn’t be in control of him alone with other minor children.

PapaSteel · 13/08/2026 13:30

He's not strong enough to seriously hurt her, he is only about 5”5 there's not much difference between them but that's besides the point. I and SS recognise he shouldn't have hit her and he's apologised but she has told niece not to apologise when she was equally as in the wrong by deliberately winding him up

I was taller than the 15 yr old who
hit me, and the consequence was disastrous.

Pistachiocake · 13/08/2026 14:45

He is a kid, not a man. He clearly does need help with his anger, which you say is happening, and obviously it's serious that he hit someone.
But a grown woman taunting a child she knows has issues? I would worry if a person like this has kids. What is she doing to them?

Hadenough32 · 13/08/2026 14:15

I work with traumatised kids and also kids that have attachment issues. Also an adoptive parent so I get the struggle. The blame lies totally with you op. You were the adult responsible. You should have told him to pack up his drawing things and go to his own room as soon as you could see he was aggravated. Or you should have very firmly told niece to leave him alone at the beginning.
It's totally unacceptable he has hit a child.
If you aren't capable of being the responsible adult you shouldn't be letlft alone with kids.
You need to take full responsibility and apologise to everyone whilst also explaining what they should have done differently. Eg your niece shiuld have listened to him. And ss should have continued to move away and not hit.
If I was your sister I would not have ss in the some space as niece any more.

Great post 👏

@PapaSteel you should really take notice of what this poster says.

DeftGoldHedgehog · 13/08/2026 14:42

A bit of a dick = no. Being verbally abusive and bullying her husband = certainly.

Well you're a terrible person in my book then. How ever will you sleep tonight ? 😆

DeftGoldHedgehog · 13/08/2026 14:42

Sugargliderwombat · 13/08/2026 14:40

I'm an awful parent and person in your book 😆😂. Calm down.

If a wife is being a dick to the husband, and so the husband punches her in the face. Does she still need to apologise for being a bit of a dick?

A bit of a dick = no. Being verbally abusive and bullying her husband = certainly.

TimeDoesntStandStill · 13/08/2026 14:42

I think for him to have gotten to 15 and not explained about how claw machines work is also an issue. From about 8 or 9 years old Ive played youtube videos explaining that theres a mechanism for full power to engage once the machine has made a certain amount of money.

Kids still like using claw machines for the fun of it but say I give them £20 per arcade session, I'll only allow max £5 to be spent on those machines per day.

Any plushies that are particularly wanted I will take a photo and use google lens to find it for sale online, show them and explain they can use their pocket money to buy it once we are home. And also when they see the plush costs £10 on amazon they are less reluctant to waste lots of their money and instead stick to actually arcade games.

Not to say he wont be lucky to get a full power claw, on our last holiday we must have spent about £20 over several days on a claw machine with kpop demon hunters plushies. Many times the claw was perfectly lined up but no power to lift it. On our last day after £2 we got a full power claw and got the plush! - but its total luck as to when this happens and your ss should have been taught this by adults in his life.

He can't get angry at the machine, thats just how its programmed, its there to make money for the business.

I dont think pandering to anger does anyone any good. It sounds like this young man has a lot of issues and I dont think being around young kids is good for him, as kids are hard work and it doesnt sound like he has the patience to be around them, which is then a risk isnt it.

@PapaSteel Your 10 year old niece was being vile and deliberately winding him up. Fair play to him that he recognised he was angry and walked away, which was the right thing to do. Make sure you praise him for this.

The problem you have here is that your niece then did not follow your instructions to stop, and continued to antagonise him. If she had stopped when asked and let him walk away, then there would be no issue. She deliberately kept pushing his buttons.

I'm not condoning him hitting her. That was wrong and he knows that. But he did actually do the right thing and walk away initially, and she did the wrong thing by continuing to antagonise him, and knew exactly what she was doing.

I have a 15 year old DS and a 10 year old DD, and in the same scenario then my DS (no anger issues) would have probably shoved his sister. And as I parent I would have made him apologise but also told my DD that if she chooses to wind people up then that's what can happen.

Your sister needs to get her daughter to apologise. What she did was horrible.

This. She should have been told off for being so obnoxious.

SueKeeper · 13/08/2026 14:41

You are minimising it because you were the responsible adult in the room and failed to manage the situation. So the six of one, half a dozen of the other splits three ways.

DN needs to learn to read social cues and not be a pain in the arse
SS really needs to learn not to be violent
You need to learn when and how to step in and actually do it, you could see it escalating, even if you'd told DN off for spilling her water SS would have felt protected by you.
