My daughter has started lashing out at her best friend. She absolutely loves her and most of the time are really happy together. There are no issues at school but occasionally when we see her after school and her friend comes round she will have an outburst and start throwing stuff at her, lucky only things like paper and also slapping her arms or legs. Sometimes she does this when friends mum is there and I feel so terrible and embarrassed by DD behavour. She never does this at school, she is very shy and almost feels like as they are very close she feels comfortable enough to express her anger in a similar way you would with a sibling. Does anyone have any similar stories or advice?
