DD 14 yrs starting to talk about going to parties and meeting friends/going to houses that we don’t really know. At single sex school but in contact with plenty of boys and girls from local schools. Completely understand wanting to hang out with friends and socialise and she’s a good girl but easily led and pretty immature. (Happy for her to hang out/sleepover with girls we know, obvs.) Checked phone recently and lots of talk from the others on this particular group chat about sex, who’s doing what/sleeping with who, “doing lines” and porn (not from her thankfully). I can already see the future and it’s not looking good. Have said no way to parties until she’s older. Lots of tears from her but better than a big issue later I think? Thoughts please? Surely it’s a no-brainier? She’s our only one and it’s all new territory but gut instinct says no way! BTW we caught her out for sending nudes to several boys over summer, had umpteen (calm and controlled) chats before and after the discovery.
