11 year old girl aggressive towards sibling

Hi everyone. I need help and advice. My currently undiagnosed asd girl is having severe trouble with noise. If her sister (7) makes any kind of vocal noise she immediately gets aggressive and agitated. She will then fly into a rage and scream at her to shut up or try to physically hurt her. 

She has taken to being aggressive towards her out of the blue to the point her sister is scared of her and I am worried that someone will get hurt ie if she were to hit or push her near the stairs or her sister were to defend herself and hurt her too. 

I can't have them in the same room together and being in the car is awful with the constant bickering and lashing out at her sister. Its like she hates everything her sister does. 

I just cry all the time because I am just so out of my depth and no idea how to advocate for both of my children.

  • I'm sorry to hear this. How old is your daughter, if you don't mind me asking? Does she have a pair of ear defenders she could use? If she is aggressive there are social stories available online which you could print and show her explaining that aggressive behaviour isn't nice or good. I hope this helps and sorry its not much. Don't give up. It's hard, I have a similar issue.
