You can only parent your own children. Both mine are best if you trust them, but know they are loved and safe.
Both know in the back of their minds that DH can spy on their internet use, he's a professional computer person. If they bother to think they know he can hack some kinds of forgotten passwords (usually his own) and all traffic passes through his machines fire wall. Not 3G, but they only had decent phones very recently.
But they know if they give him or me no reason to worry he won't and that suits them just fine.
The more you helicopter children, the more likely they are to do something stupid in a rush egged on by their mates.
No you can't unsee porn, but compared to being investigated by the police for circulating a naked picture of your mate it's small beer.
DDs been thinking about what she posts almost as long as she can remember, I hope it means she engages her brain.
Certainly the internet, social media and messaging her mates is normal and not something to get giggly and silly over.
As for DD1, she has been on the receiving end of so much shit for being quirky and dyslexic, that she only talks on line to a few very good out of school friends.
Her only internet 'crime' was watching the vampire diaries and torch wood when a bit young. Given a bad habit of reading her way through the sixth form library shelf, I'm not going to fuss.
