Though my kids have never made a big move (when I say big, I'm talking moving long-distance away from friends and family), they have had to move from one house to another.  It was hard on them. They missed their rooms and the familiarity of their surroundings. But it was minor compared to what some families go through.  Now that my daughter is in 1st grade, I can't imagine a conversation telling her that she's going to move away from the home she's known for years, her family and her friends at school.  If that's the situation your family is in, consider checking out books that were designed to help kids get through the stress of relocating.  Here are some recommended books, listed by age.
