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

So you expect an older sibling to stand by and watch their sibling being bullied

If I saw a 15yo turn up to a junior school to thump a Year 5 I would think that was insane. At 15 you know to tell an adult. Are you really saying the only way to keep a sibling safe is to put hands on someone else? What does that teach them?!

You appear to have grown up in some sort of alternate universe where you think it’s normal/fine to be like this as a teen and grow out of it.

It really isn’t.

The thinking is clearly warped.
Tis to be pitied really.

Dn is only 10 she doesn’t know/understand his struggles and won’t necessarily recognise he was getting overwhelmed.

She is old enough to understand 'No' and 'Stop it', that name calling is unkind, and that when someone walks away, they don't want you to follow.

It seems he shoved her shoulder as a last resort when walking away didn't work. What else could he have done to make her leave him alone?

I was giving both sides . I agreed she should have stopped when op said no

Aiming4Optimistic · 14/08/2026 08:53

I think it's important to remember that he pushed/shoved her, after a great deal of provocation and no adult intervention which, although not acceptable given age and size difference, is absolutely not the same as punching her in the face. Some posters are using words like 'assaulted', and talking about calling the police or banning this child from being near OP's own children, as if he attacked her and caused actual injury.
Going on the assumption that the niece isn't physically hurt (because I think OP would have included this info if that had been the case), people need to stop equating this with domestically violent adult relationships or their own experiences of child abuse and remember that these are both children - the son as well as the niece. He needs help to manage his past experiences and how he responds to situations. He doesn't need to be treated as if he he's an adult male with a long history of attacking women!

CinderellaGotOld · 14/08/2026 08:46

I just wanted to say I think it is awesome you are supporting your ss - you can’t give up on kids and youve made clear he is getting help and taking steps to get himself out of a situation he knows could escalate. Your dn sounds a complete brat. If you sis had so many concerns about him being around then maybe she should have been parenting her own child rather than leaving her with you and (5 was it) children to look after. I can also see you are not saying he shouldn’t have hit and he knows that too. I do perhaps think you could have taken more steps to get you dn away though. Whilst she knew exactly what she was doing and should have stopped when you told her not to, the fact is she didn’t and so you should perhaps have upped the level of interference there.

I'm not blaming her for being hit but she's not completely at fault. She wasn't just being annoying and even if she were she should have stopped when I told her and when he told her to and when ss walked off.

I've already said he was at fault for hitting her butposters on here are making out as if he walked up to her and hit her for no reason whatsoever

There is NO reason for a 15 year old boy to hit a 10 year old girl.
You are not getting it. This behaviour is completely unacceptable and you need to remove him.

Imagine him in 10 years time in a relationship. He lashes out because his gf was ‘winding him up’. Come on… STOP minimising this. Stop enabling this. Get a grip and recognise what you are raising - an abuser, now and into the future.

God, I hope my girls are lesbians.

TheFairCat · 14/08/2026 08:18

@Anyahyacinth apologies I think I am occasionally confusing your posts with another poster who has a similar writing style and is saying broadly the same things.

I think it was you that said that the behaviours leading up to violence are irrelevant and that is not true at all. They are not considered irrelevant in the legal system or any other formal context.

The behaviour of all parties concerned and the circumstances preceding violence are all important factors when assessing future risk and considering underlying pathology and patterns of behaviour.

Whilst it is true to say that all acts of violence are unacceptable that does not make them all the same. An adult man beating his daughter with dog leads is not the same as a child hitting another child after repeated provocation in a confined space.

The context can help us to assess future risk. In this case the wider context is a child who has only recently been removed from an abusive situation, is having help to manage his difficulties with emotional regulation, is in a loving and supportive home, has a good relationship with his step siblings (and has demonstrated no violence within the home), is managing well at mainstream school with help and has a good group of supportive friends.

She should apologise for being rude and damaging his art work. And to her aunt for being rude and ignoring her.
This isn’t an adult who should be able to control his emotions. It’s a child who’s working hard to become a better person having had a shit start to life.

There are things that can be excused for sure, but I draw the line at a teenage boy hitting a little girl. We are what we do and the endless excusing of violent behaviour doesn’t wash.

MaIeficent · 14/08/2026 05:21

I think a lot of kids that aren't abuse survivors would have struggled to walk away in this situation and would've done more than just shove her shoulder. Niece will actually get hit properly if she does this kind of stuff to other girls who haven't been told all their lives that it's wrong to hit females.

You appear to have grown up in some sort of alternate universe where you think it’s normal/fine to be like this as a teen and grow out of it.

It really isn’t.

Sparrow7 · 14/08/2026 06:08

What exactly do you mean by he hit her? There is a big difference between a slap on the arm or a punch to the face? Was she hurt? It's hard to gage if DS is over reacting without the specifics.

whoopala · 14/08/2026 06:02

Oh dear.

People wind other people up all the time. It doesn't mean you are entitled to smack them one.

"It's okay son, she was asking for it", is a messed up message to give.

Making excuses for such retaliation is how abusers are made.

Not to mention, one day he will retaliate against the wrong one, someone who also feels justified to violently retaliate, and end up with his head weaved into the floor.

likeitshard · 14/08/2026 05:37

Both of you are right.

you are correct that your ss is a troubled young man working on his issues having been dealt a shit hand in life and that he deserves empathy and compassion.
your Dsis is right to expect her dd not to be physically assaulted by a older child even if said child is a brat. Dn is only 10 she doesn’t know/understand his struggles and won’t necessarily recognise he was getting overwhelmed. He was wrong to hit her.

i would leave the holiday, its not good for your ss to be around people who clearly dislike him and don’t include him in the family.

Maybe for now see your sister separately on your own (or possibly with your younger children) your ss doesn’t need people like that in his life.

Yes he is. His height is irrelevant.

I wouldn't have made the girl apologise either

And that is disturbing, more than anything in the OP.

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

No female should be apologising for being hit by a male. You are so wrong.

Wisher88 · 13/08/2026 15:45

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.

So you expect an older sibling to stand by and watch their sibling being bullied

Yes, precisely. A school day for me. Based on pronunciation alone I believed it to be ‘desserts’, and I was wrong.

If not diving particularly deeply into English language idioms makes me dumb then alas, I’m guilty as charged.

A 15 year old boy shouldn’t be hitting a girl 10 year old girl despite his age and despite whatever she has done to antagonise him. He sounds like he has anger issues and you might need some additional help with him. Fully commend you for taking him on, it must be difficult,
