Prejudice often begins when children develop misconceptions based on their limited experiences. Answers should be simple and relate to a child's experience and level of development. You have blond hair just like your mother. Many people were taught as children not to stare. They were taught so well that they avoid looking at people with disabilities at all.
Some children are afraid of the unknown.
They may have wrong ideas about people who are different. They may be suspicious of unusual people and resist the new and different. Fears should be accepted, and children should be offered help to deal with their fears. Helpful responses acknowledge the child's feelings. Then give the child the tools and experiences to help her deal with her fear.
