You will have plenty of time during your last two years of medical school, to know if pediatrics is the thing for you! As a critical care pre hospital provider, we work with quite a few pediatric patients. They were never hard, for me. The hardest part about pediatrics, is learning how to deal with the parents, including health workers who are parents. If you can calm the parents down, the child will calm down. And not just in critical care. If you are sort of calm and laid back, the parents usually calm down. I’ve never had a scary moment with children. If I do, it’s time to stop treating them in the medical field.
If you want to know now, if pediatrics is right for you, work at day care for a while. When you get out of high school, become a medical assistant in a pediatric office, or become a tech at a pediatric hospital. Work the switch board at the hospital, if you have to in order to get your foot into that environment. Most people who work at a ped. hospital are there because they want to be and they are good at it.
