&quot;What do you imagine your parents did? And parents for all of human history before the last 20 years?”&quot;<p>Many things were different 20 years ago. Today being a parent of 2 toddlers, I cannot even imagine not having a phone with me when my kids are away at school&#x2F;daycare. No I am not paranoid. I trust the school&#x2F;daycare. But that one instance of time when my kids need me asap and the school could not get to me quick enough, I will never forgive myself for that. Just for that kind of emergency, I will have my cellphone.<p>When it comes to kids of your own, it changes a lot of things. I will never take a chance with my kids.
