My daughter is 10 years old and wants a mobile phone (mainly because some of her friends at school have them). I have told her when she starts secondary school she can have a phone as she will be travelling on her own.
Some parents don't seem to be able to say no to their children and I have seen children at her school as young as 6 walking around with the latest iPhones, this is society gone made surely when parents cave in and can't say no to their children.
