If your child hears of a fire, storm, or a violent crime let him or her know how far away it is. Well it would take three days and three nights to drive to where the storm is. Respect your child's feelings. If he is afraid to pet a dog you might suggest that he might want to try it later. Do not use stories of the bogeyman.
Children think they are real.
Practice what to do in case of a fire or tornado. Knowing what to do can reduce fears. Ease your child into new situations. Prepare her for things that might be scary. Showing pictures can help.
