I would be doing the same as you Tinks. These days with fb and cyber bullying its better to avoid the late nights fitting on the computer. It's very different to when we grew up when it was just the TV in our rooms. There has been a lot of media coverage lately about kids using their phones and I have a friend whose daughter was messaging dark thoughts etc and started self harming once they took the phone away and started talking it has stopped. Just because you know the passwords doesn't mean you will look either. Although my kids are little dh runs an IT business so we talk about it all the time and our rules will be similar.
