Pediatric doctors specialize in providing care for newborns, children, and teenagers. Pediatricians provide well-care and sick-care, give immunizations, and provide developmental care as your child continues to grow.  Providing not only physical care but also emotional and moral support.  They must understand child development, the difference between pediatric and adult medicine, and how to communicate with patients who might have difficulty expressing themselves or grasping the significance of their situation.
