A neonatologist is a medical doctor who specializes in the care of newborns, particularly those who are ill or born prematurely. They work in neonatal intensive care units (NICUs) and are trained to handle complex medical issues that affect newborns, such as breathing problems, infections, and birth defects. Neonatologists collaborate with other healthcare professionals, including pediatricians, nurses, and respiratory therapists, to provide comprehensive care. Their goal is to ensure the best possible outcomes for vulnerable infants, often involving advanced treatments and monitoring to support their growth and development during the critical early days of life.
