My son is friends with a boy from his school (they're 7), I'm friends with his mum although not close, our children do a club outside of school together so I often pick up her son and take him to it, he also comes to our house often for playdates.
Over the summer, her son seemed a bit upset and when i asked him what was wrong he told me his brother (15/16) was drinking the night before and his mum was shouting, I put this down to a one time thing although it happened again a few months later and this time he told me that his brother had hit his dad. Around this time, my friend was telling me about how her son was refusing to go to school and his behaviour was getting worse.
This morning, I picked him up from his club and he seemed upset again and he told me his brother was drunk last night and swore at him and tried to hit him and he told me that his brother is drunk a lot and always horrible to him and his mum.
WWYD? WIBU to report my friend to safeguarding?
