The National Library of Medicine of the United States offers these suggestions:
- Give your child a detailed explanation, simple and clear what will happen.
- Be specific about which part of the body will be affected, and as you might feel.
- Allow your child to react, even if it includes anger, screaming or crying, but encourage communication about what he or she is feeling.
- Have your child practice the positions that will be required, for example lying down or stretching one arm.
