Pediatricians,just like brain surgeons,heart surgeons and all other physicians,go through 4 years of medical school,a year of "internship" and at least a year or two of additional training.Some specialties require many years of "post graduate training"...I think heart surgery is something like 8 years...and others require only a few. General pediatrics,I think, might be one of the latter.
I don’t think people really care what training they go through. That’s not the problem they are discussing in this thread.
