My daughter just unloaded as I was reading her bedtime story (yes she's 13 and still likes a story at bedtime), she said one of her friends was drunk on arriving at school and had told her she's been drinking vodka and lemonade all night as her dad was scaring her. My daughter poured the contents of the drink bottle away and brought her a bottle of water; they aren't in any classes together and she didn't want to get her friend in trouble by saying anything. She said this child has regularly told her that her parents scare her and she doesn't feel safe but has lots of siblings and wants to make them safe. My daughter says she's got bruises on her body that they see when they change for PEand she is always scared and "scratchy". What do I do with this information? I was going to email the safeguarding lead but not sure whether I'm over reacting? Tia
