As you probably know by now, doctors who only treat kids are called pediatricians. They’re the ones who best understand that children have different kinds of medical needs than adults. Kids catch diseases that adults don’t get (think chicken pox), they’re very active and get more sprained ankles and broken bones, and they’re more scared of things like shots and needles. (Although who really likes getting shots ever?) So pediatricians not only have to know how to heal a kid who’s sick, they have to be good at making that kid feel safe. As with any doctor, you need an advanced degree and a special license to practice medicine from the state. This is a great, high-paying career if you love kids and dream of being a doctor. Plus you can even wear clown shoes if the mood strikes.
