Ooh, quality comment. You’re getting good at this curating stuff @bec-on-the-block!
It’s honestly hard to say. My girls are still young, so this isn’t something I’ve had to face directly yet. I think that from what I’ve read, I would emphasise having a relationship with your kids where they feel they can share things with you without fear of being judged. They will never tell you everything, but the more they open up, the more likely you might be to catch something before it goes too far.
