Pediatrics is the medical specialty focused on the health and well-being of infants, children, and adolescents. Pediatricians diagnose and treat a wide range of childhood illnesses, developmental disorders, and injuries. They provide preventive care, immunizations, and guidance on growth and development. Neonatology is a subspecialty of pediatrics that focuses specifically on the care of newborn infants, particularly those who are premature or have medical complications shortly after birth. Neonatologists manage conditions like respiratory distress syndrome, jaundice, infections, and birth defects. They provide specialized care in neonatal intensive care units (NICUs) to promote the health and survival of newborns.
