Aside from leading by example......I also make things a game. I am by no means the "model parent", but my kids garden with me, they go picking berries and help make sausage, stack wood, dry food, etc.....and we live in the city. We don't mandate a lot of work out of them, but they pick up a bit. Honestly, our daughter brags to her friends at school how much stuff we do for ourselves and how much we don't get at the store ready made.
I have a 2 1/2 yr old and an 8 1/2 yr old and we decided to start making perparedness fun. We have started having "no power nights". It's amazing how well they adapt, and they see it as fun. They play games carry around the flashlights, we eat by the oil lamps. It's a good dry run and we learn a lot too, we learn where things are, what we are missing, what to get next, how to pass the time.
Still working on BOB's for everyone, but my daughter carries umbrella, gloves, jacket, snack, hat in her school bag......she used to ask me about why I made her carry it all the time.......not so much anymore, she's getting it. The other one that is sinking in is dad's favorite phrase......."situational awareness".......I don't mind her being goofy, I just want her to be aware of what is going on around her. They do pick up on this stuff through repetition.
