I've raised my little mini me to young adulthood now, she's about to turn 22 in a couple of months and I'll second what you say about the importance of communication. We definitely can't keep them safe from all harm, so the compassionate thing to do is arm them with the tools and knowledge the need to navigate the world, online and off, then trust them enough to explore safely. As a father I found it really tough having to explain the nature of the world to my beautiful innocent little girl, but she grew up taking heed, thank God.
