Neonatology is critical because it ensures that newborns start life as healthy as possible. Advances in neonatal care have significantly reduced the mortality rates of preterm and low birth weight infants. It also plays a crucial role in identifying and managing congenital anomalies early, providing timely interventions that can improve long-term outcomes. The specialty requires a deep understanding of physiology of newborns and the ability to manage complex medical issues that arise in this vulnerable population.
