What cles do you need to take in college in order to become a Pediatric doctor?

You're getting ahead of yourself. You need to focus on getting into medical school at this point, not your specialty afterwards. It may seem to you that you should take college cles in child development or some such, but it doesn't work that way. Check the AAMC website for different medical schools' requirements. There really aren't that many, and you can pretty well take what you want and major in what you want in college as long as you get the minimum requirements. There's really very little advantage to taking college courses related to pediatrics. You have no idea at this point how intense your training in medical school and residency will be. You'll get what you need when you get there. Enjoy college, and take cles that will make you a better person, not a better pediatrician.
