Hello. Remember a pediatrician is medical doctor. I cannot recommend schools because that is not giving you a clear answer. What is good for me, may not be good for you. There is a lot of science and math involved in Medicine, so being strong in those subjects is important. I would suggest speaking to a high school counselor, or doing internet searches to see what schools are in your area and what are the requirements. To go to medical school requires a Bachelors degree in pre-med, biology, or other science field. Then there is four years of medical school, three years of residency and an additional 2-3 years of fellowships depending on what specialty in pediatrics you choose. That is 13-14 years continuously in school from the time you graduate high school. I suggest you do your research so you know everything that will be expected of you. That will help you make an informed choice.
I hope this answer helps,
