At what age is it appropriate for a child to receive a cell phone? I am flabbergasted that my ex-husband told me yesterday when I picked her up that she had earned the money and privilege of having a cell phone - SHE JUST TURNED 7 in Aug!! What would you suggest, how do I deal with this, I believe it's completely inappropriate. My son received a cell phone when he was 11 because after school he was home alone for an hour before I got home from work and there was not a land line in the house. He lost it over the summer and I am refusing to replace it, he doesn't have any need for it any longer, he is never home alone. I have joint custody of my daughter and my son will find this very upsetting if she has a phone he can't have.
