I'm a mom to a three year old girl, stepmom to 3 teenage girls.
You're already a survivor. Mothers of teenagers are among the toughest people around. That's a survival situation I haven't faced. I'd sooner deal with a month-long power outage in July.
Also check out this blog by a mom who became interested in preparedness and in classic achiever-mom fashion, is learning everything she can and sharing her knowledge.
http://thesurvivalmom.com/Susan got you off to a great start. It helped me to organize learning and prep around the basic tenants of survival.
Welcome aboard! Good to have another chick around here.
