My DS aged 12, was upset last night. A so called friend repeatedly keeps saying to him he has no father. I have heard it once whilst they were gaming but I’m told it happens regularly. I have offered to contact his mother to say this needs to stop. My DS said I should let him deal with it. He said he will be firm with his friend and tell him he can’t say that anymore. I don’t believe he will. I fear it will carry on. Should I contact the mother?
