My sister and her family recently moved to tornado alley and she is somewhat frantic about getting her family prepared. I've never lived where tornadoes would be an issue for me and I'm at a loss as to what to help her with. I'm mostly interested in helping them prepare mentally as I've already sent her all the information I had on general preparedness. So, what do you all do to keep the family from having nightmares about tornadoes (or other natural disasters)? I'm especially interested in any information you might have on helping children cope.

Thanks!
