My dd2 (13) has Social Communication Disorder. It was very difficult during her time at Nursery, shaky during Primary but seems to have levelled off now she's at Secondary school.
The problem is her temper has got much worse lately. Perhaps due to hormones? She gets frustrated very easily, shouts, stamps her feet and throws things but the worst of her anger seems reserved for Dd1. She hit her in the face with her phone charger last night and gave her a big lump in the forehead 
.
I have withdrawn her privileges (mobile phone/laptop etc) as punishment but I feel that is treating the symptoms not the cause. When I try and calm her down I just end up making her worse!! Any advice would be much appreciated.
