Which major will benefit me or prepare me to become a pediatrician?

Hi My-an! You don't need to major in anything specific in order to get into medical school. However, you do need to take certain classes (biology, chemistry, physics, etc.). Even the classes depend on which school you want to get into, but most of them should have similar requirements.

Because the required classes involve so many sciences, lots of people major in Biology, Neuroscience, Chemistry (and many more depending on what your college offers), because it kills two birds with one stone. For example, as a Biology major, many of the classes you need for graduating are also the ones you need for getting into medical school.

Not every undergraduate institution offers the same courses, and not all medical schools are looking for the exact same classes. I would say to focus on the med school you want to go to and look up what classes they require. Then, find a counselor at your undergrad and talk through with them what classes offered at your college would satisfy the requirements of the med school. Sometimes, courses are named differently and you might be surprised by what does/doesn't satisfy requirements.

Another super important component of getting into med school is also doing research! Undergrad is a great time to explore lots of different fields of research. When you're in med school, your main focus will be on health, biology, and medicine. So feel free to use the time you have now in undergrad to explore other topics! Your research does not need to be science related. Research is supposed to teach you a different way of thinking, problem solving, and how to work as a team. If you are interested in Psychology, Geology, Art, or anything considered a bit "non conventional" or "off track", I encourage you to go for it! After all, your application will probably be the one that stands out the most!

Good luck!
