What kind of doctor should i become? i'm interested in pediatrics, the er, and paramedics. can i have some background on each of those?

Follow your passion: You will have plenty of opportunities to "taste" many different specialties when you do your rotations in the third and fourth year of medical school. You might be surprise with what you end up liking!

Depends: Well it really depends on whether you want to be a doctor (pediatrics and Emergency Medicine) or a health professional (paramedic) . As a physician/doctor you will have to complete college (4years) and med school (4years) and then residency after that (where you would specialize in either pediatrics or emergency medicine, etc). For paramedic there is MUCH less school/training required.

Pediatrics: Pediatrics is a very rewarding but demanding lifestyle. You almost always have call and need to be prepared to work long and hard hours. Babies that need help and care after birth don't follow office hours - you can spend all night awake. But there is no feeling like saving and curing that newborn either, to know you are a miracle worker. ER docs don't have as much call-do their shift and home.

Peds ER?: While no one can tell you what to do with your life, have you considered combining the two and going into Pediatric ER? It usually involves a residency in pediatrics then a fellowship in Pediatric ER.

Don't Narrow yet: These are great ideas, goals, and questions. But, my only advice (I know that you have several answers here) is to not limit your experience in school and medical school to just these narrow interests. Let your experiences shape you, let you be called to a field of study and work;. let the patients and the culture of medicine take you to your life's purpose. It may be in Peds, or ER, or not.

Specialist : you could work towards a board certified pediatric emergency room physician. Help train paramedics

Emergency Medicine : I am a pediatrician for over 20 years. In my opinion, the way medicine has changed and is continuing to change, I think ER medicine would be your best choice.
