One of the best ways to prepare and to get your family on board with preparing for an emergency is to include them in your preparations. This may seem a daunting task, but as Phil801 has shown us with his eight children, it can be done. Just look at some of his How-To posts to see evidence of them helping out.
For some of us though, we may just be starting out, or we may not have our family on board with what may be for some a significant lifestyle change. Fortunately, the LDS church which has always urged preparedness from its members has had the foresight to put together a series of family friendly preparedness activities which are perfect for those families just starting out.
