Book excerpt: Elmo and his friends, Dr. Lana, Nurse Nick, and Nurse Christy, show kids how doctors and nurses take care of kids in the doctor’s office, a hospital, and in school. They take the mystery and fear out of a visit to the doctor’s office by demonstrating the basics of check-ups and explain how doctors and nurses help children get well when they’re sick and make sure they stay healthy the rest of the time.
