To think Dsis is overeacting after SS hit niece?

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

OP's excuses so far:

He's had a troubled upbringing
It was the 10 year olds fault for being annoying
He didn't punch her he "only" hit/pushed her
He's apparently not strong enough to hurt her
He apparently wasn't being aggressive when he assaulted her
He didn't shout in her face, he only shouted at her

Anything I've missed?

You are not just part of the problem here OP, you're a huge contributor. I highly recommend you change your ways because very soon he will no longer be a violent 15 year old, he will be a violent man. Very dangerous.

OTT.

@Duskiestsunset I certainly wouldn’t want her as my 10 year old. Awful behaviour. Her parents should be ashamed of their parenting.

Whilst SS shouldn’t have done what he did but equally neither should the 10 year old who sounds like a bully egged on by her mother. (I wonder what she id like in school towards those she thinks of as less than her)

She knew how to wind SS up. I would be going very low contact with her mother and NC with the niece

For her own DD’s safety your sister needs to teach her DD that just because she can bully someone she will have to expect a response in return.

If she is 10 years old She will be going to senior school probably next year. If she continues this behaviour she could target someone who has older sibling/s who will protect their younger sibling. And a slap is the least of her problems.

I might get shit for this but in my experience bullies always seem to know exactly who to target.

I would want to call the police too if a 15 year old boy hit either of my DDs. They certainly wouldn’t be socialising with him again.
Absolutely disgusting behaviour, he shouldn’t be around younger DC unsupervised again.

Can’t believe the number of people justifying this because the girl was “being annoying”.
To be fair she probably was but also is 10 and behaving like a normal child which is not perfect.
No wonder we have such a problem with VAWG in this country.

In 10 years time OP and her DP will be justifying this boy hitting his girlfriend because “she did xyz” 🙄

Exactly

and I very much doubt it would just be limited to hitting

Adossieronme · 13/08/2026 15:46

landofstories · 13/08/2026 15:43

Never.

I never would. I don’t believe in hitting. Doesn’t mean there weren’t times that they didn’t deserve a slap. Just not in my nature to hit and fortunately I could count on one hand the times they (between the 2 of them) probably fell into this category. They are now almost adults.

It all sounds a bit…. Well, “she deserves a slap but I held back” Sounds a bit “wife beater-ish” to me

IsItSnowing · 13/08/2026 15:45

You’re being deliberately vague about what you mean by hit but I’m assuming you don’t mean a shove and that he actually hit her. Not that laying hands on another person in anger is ever acceptable.

What is really worrying is that you’re looking for excuses - there are none. There are reasons but they are for you to deal with to help your DS. Nothing excuses violence. Victim blaming might make you feel better but it’s pretty shitty behaviour.

Your niece is a brat and that needs dealing with by your sister. Your DS list the right to an apology when he assaulted her.

lots of people in life are annoying. We don’t get a free pass to assault them. He may get away with it a few times. Sounds like he may get away with this because you’re determined to minimise. Eventually he’ll assault the wrong person and then he’ll find out the hard way that he can’t go round hitting people. He’ll either get hit back and maybe seriously hurt or end up in prison. You’re doing him no favours at all by downplaying it.

NerrSnerr · 13/08/2026 15:45

The 10 year old was very naughty and should have been removed from the situation much earlier, especially with your step son’s anger management problems. He absolutely shouldn’t have retaliated though and you need to come down on him hard. I know he has past trauma but if this is minimised it gives him the green light to punch someone who annoys him again. When he hits his girlfriend, wife or child it will be ok because he was provoked.

Yes, when managing his behaviour everyone needs to be trauma informed and be hugely aware of his past- but part of this is removing the triggers and working with him when he is stressed and angry (like going for a walk when in the arcades). You clearly weren’t able to do this today.

Don't forget to tell her if she wears dresses she can expect to be raped too.

If she's going to school and winds up a child her own age I would expect a child her own age to respond, not one several years older.

Duskiestsunset · 13/08/2026 14:00

Goodness me. I can’t believe these replies. She snatched his drawing away after he told her what it was because she thought her right to see trumped his choice, then spilt water on it and then walked after him being deliberately nasty calling him a crybaby. And everyone here is falling over themselves to excuse it and say no need to apologise.

she needs a good smack to be honest. She sounds awful. Complete overreaction. He’s hardly a violent man. He said sorry, needs to know he can’t do that again - but she sounds far more unpleasant and spiteful. No wonder society is going downhill with alll these posters bringing up their children like this.

OP don’t holiday with your sister. She sounds vengeful and horrific.

👏👏👏👏👏👏💯

Ponderingwindow · 13/08/2026 15:44

He is 15. When it comes to violence, he is not a child.

Our holiday with you would be over. We would not leave, but we would not spend any more time with your family.

Your blasé reaction to this is frightening.

Why didn’t you tell the 15YO to move away then? You’re clearly exaggerating how badly behaved she was being because no mother figure on earth sits there whilst a child is that unpleasant to their own child!

He was moving away and she decided to follow him and continue taunting him.

HumberSquid · 13/08/2026 15:09

She was pestering him.
Wouldn't take no for an answer
Damaged his stuff.
Then, when he walked away, she followed him jeering and taunting him.

I think that actually is quite a lot.

She's 10 😂 I don't doubt she's a wind up merchant, but really the responsibility lies with the adult overseeing them and the 15yo. Once you clump someone you lose the right to an apology.

I wasn't just sat there, they were across the room and I was feeding my baby. I told niece many times to stop it/leave him alone/go do her own thing but she didn't. She's a few days off 11, not a toddler she shouldn't have to be physically removed as posters have suggested by me grabbing her by the arm (and sister would likely have found issue with this anyway). She's old enough to know when to leave people alone and respect boundaries, she's going into secondary school.

At school if she's told no and to stop doing something she won't be removed by a teacher (not physically anyway)they just expect her to listen and do as she's told.

Why didn’t you tell the 15YO to move away then? You’re clearly exaggerating how badly behaved she was being because no mother figure on earth sits there whilst a child is that unpleasant to their own child!

IronEverything · 13/08/2026 13:32

Yes he is. His height is irrelevant.

I wouldn't have made the girl apologise either

But I would. People are not toys that you wind up and not expect consequences. She was baiting him. Unacceptable behaviour. No, he shouldn't have hit her but she's well old enough to know how to behave. He's apologised, she should too.

LostNFoundSV · 13/08/2026 15:38

News flash! He is “the bad guy”!
Do you honestly believe that telling a girl that it’s okay to be hit (it doesn’t matter how hard or soft) for annoying someone is not a problem?
Can you seriously defend any man or boy using violence ( no matter the level) against a woman or girl because “she pushed him to it”?

Adossieronme · 13/08/2026 15:37

landofstories · 13/08/2026 15:36

Many children deserve a slap, but it’s something we wouldn’t want to inflict on them - they are ofcourse just children being highly annoying.

Bonkers1966 · 13/08/2026 15:37

Both young people sound insufferable. I wouldn't allow them in the same space until they are in their twenties.

Jellybunny98 · 13/08/2026 15:36

Niece sounds irritating but it feels a dangerous route to go down to even remotely suggest to a 15 year old boy with anger issues that it’s okay or in any way acceptable to hit someone just because they annoy you.

landofstories · 13/08/2026 15:36

Adossieronme · 13/08/2026 15:34

No, she did NOT deserve a slap FFS
