DDs friend sexting - what to do?

[BlueonBlonde]

DD is in Y8, I have always said I will check her phone if I had any concerns about her behaviour but have rarely done so. She was abnormally glued to the phone over half term so I decided to take a peek. No concerns about her arose but from a chat with one girl it seems that this other girl has been sending naked photos to a boy (sounds similar age) she knows. Obviously this is quite concerning at her age but I’m not sure what I should do about it, given I don’t know the girl or her parents. Any suggestions?

I'd contact the school, and get them to inform the parents. Someone at that age doesn't realise the repercussions that can happen.
Also as someone who was over sexual at a young age, I was being abused/ was abused as a young child, not the case for everyone that does something like this as a teenager but I think that's why it's so important to tell someone just incase.
