Most doctors did not like to treat children. This was because tasks related to pediatrics were complicated, and a doctor needed to be a jack-of-all-trades to be able to treat a child well. Besides, children either had not learned how to talk yet or could not express themselves properly. This made it difficult for doctors to make a diagnosis, and hence, the Pediatrics Department was also known as the Mute Department.
In addition, the family members of children were getting more and more demanding. This was a widely accepted fact.
Of course, the main problem was because even though pediatricians had to work very hard, their income was low. In the field of pediatrics, medicine was rarely prescribed and there were very few surgeries. In most hospitals, the salary of pediatricians was less than half the salary of internists. Even after the healthcare reform, the pediatricians' salary was still around only half the salary of surgeons.
