At what age do people teach their kids to use the phone? I'm going to be on my own for a bit with my two DSs while DH is away on a work trip and I've been worrying about what DS1 would do if anything happened to me. I'm wondering whether I should teach him to call my mum in an emergency. So far I've taught him not to touch the phone and he doesn't. He's pretty sensible but I'm not sure if he's too young.
