Not sure what to do my DH came home today with huge scratch (chunk of skin missing) on his forehead teacher said boy was teasing my DH and he pushed him and other boy went mad hitting and scratching DH, not first incident involving my DH and other boy but teacher says they will work it out, not sure what to do, the mum is a friend but as she works full time and doesn't do school drops or pick ups don't think she's aware, my DH has really lost confidence over last few months. A mutual friend has said she's stopped her little one from playing with the boy as he's too aggressive, help not sure how to proceed
