my daughter isnt allowed to bring her phone to school with her. wen shes 11 and goes to secondary school she will be able too though,this will make me feel a lot happier because i feel she will be safer with it on her, alot of kids get their phones stolen from them i know, but the way round that is not to get them the top of the range,thus stopping temptation from the other kids.,its the way of the world but i dont let her play out unless she takes her phone with her.if she strays out of sight for a second im on it going"why cant i see you?".
i think the idea of leaving them in backpacks is a good one i dont see a problem with them having them in school just as long as thet arent distracting the class with them
