Axis founder David Eaton encourages parents to talk to their kids about appropriate cell phone usage. Eaton reminds parents it's not so much about how to use the phone but why we use it. Eaton also lets parents know some non-negotiables for kids regarding cell phone use, like porn and sexting, and helps parents coach their kids on how to stay safe online. David Eaton is a contributor to Dennis and Barbara Rainey's book, "The Art of Parenting."
