Telling my wife’s sister child off

[Hillwood2012]

I am writing on this forum to get some clarity, last night my wife’s sisters daughter who is nearly 7 was over for a sleep over and she started to have a massive argument with her mum in my house…. It started to get worse over time… she was attacking her and swearing eg F word and S word really loud punching my walls at this time. I was upstairs with my 7 month old baby trying to keep her away from the shouting. Then my wife, sisters daughter came upstairs shouting…. I told her Nicely if you want to do this please go down stairs….. then she came and screamed in my face and my daughter face at a high pitch scream…. So I I lost my temper and shouted at her to go down stairs now as I had listen to her screaming for ages at this point and she was running rings around everyone…. And it was getting late…… and now everyone is at me saying I’m the bad guy as I just wanted her to stop as she was scaring my children

Id be quite relieved with the solution that the child will no longer have anything to do with you or your kids. Sounds like a win to me!

How did the Sister ever think it was acceptable for her child to behave in this way? Any reasonable person would have had her out of the house and home the minute she started.
These 'gentle' parents have a lot to answer for - they may gentle away their offspring's awful behaviour, but those kids will soon learn that other people will not stand for it. Those kids are in for some nasty shocks, and it is the fault of the parent.

I've had exactly the same situation as the op, but with my 10 year old nephew.

Nephew was bullying my DD (7) and I was the one who told him off.

His mother, SIL, hasn't spoken to me since. Because I had the audacity to tell him off, when no-one else would.

According to her, he shouldn't be told off, because he's autistic.

He regularly hits/swears/causes chaos/has his own room at elementary school because he's uncontrollable, but no, he shouldn't be told off because he has autism.

I despair.

I agree. It's enabling and a disservice to the child.

There was another similar thread on here a few weeks ago, a woman on holiday with family whose child was autistic and parents refused to control her.

It's a real problem.
