What major should I take to work in pediatrics?

You don't need a major, you don't need a degree, you need a certificate.

Health care doctors need to take the health care doctor's certificate and nutritionist's certificate. It is better to have a degree, and medical related majors are the best.

At first, the salary of health care doctors was low, and they needed to accumulate work experience to grow up. Wages in kindergartens are generally low. As for the lack of experience, it needs to be accumulated. But you need to take a health care doctor's certificate, preferably a nutritionist's certificate.
