Due to somethings I've seen over the last few months few months I've been concerned about a little boy at my son's school. His mum appears to have an alcohol problem, and after seeing her with him clearly very drunk just after the school pick up I decided to talk to the head teacher at the school about my concerns. The mum has gone mental and been putting posts on social media that she will hunt down whoever has done this and make them pay. I'm worried myself and my son could be in danger now. The school said it would be on confidence but I'm unsure what to do. Any advise?
