I am having various confrontations with my son about his mobile being on late into the night. He used to go to bed around 10ish to read now all he seems to be doing is messing around on his blackberry! It's driving me insane - do you think I am right in taking the phone away and turning off at an appropriate time - he thinks I'm weird because I want his phone all the time - he seems to have definitely changed into a grump teenager. He doesn't come out of his room much and socialise with us and is very secretive about a lot of things when I ask him about facebook/mobile etc. How do I handle this - any comments please?
