A neonatologist is a medical doctor who specializes in the care of newborns, particularly those who are ill or born prematurely. They work in hospitals, often in the neonatal intensive care unit (NICU), where they monitor and treat conditions such as breathing problems, infections, and birth defects. Their training includes completing a residency in pediatrics followed by a fellowship in neonatology. Neonatologists collaborate with other healthcare professionals, including pediatricians, nurses, and respiratory therapists, to provide comprehensive care for vulnerable infants. They also support families by offering guidance and education about their baby's health and development. Their expertise is crucial in improving outcomes for newborns facing serious health challenges.
