14yo DS and I have a running battle over this. I make him hand over his iPhone at night and put it on charge in my bedroom. He says none of his friends' parents do this and if perverts, drug dealers, bullies and terrorists want to target him via his phone then they can do it just as well during the day. I tell him that I don't care what his friends' parents do and he needs to be able to sleep without those people having access to his room. Quite apart from him using it to play games at all hours of the night!
Does anyone other parent take away phones overnight, or am I truly the only parent in the universe who does this? Apart from my next door neighbour, who does it too...
