There are lots of different kinds of doctors. I am a pediatrician, which means I take care of kids.
I often see kids for regular appointments. At these check-ups, I'll do a simple exam to make sure your body is running smoothly.
Other doctors work with kids who might need certain kinds of care. For example, some doctors work with your heart, your bones, your eyes or your lungs.
Doctors study medicine for a very long time, so we really know our stuff. Feel free to ask lots of questions (and to share a good knock-knock joke!).
