Neonatal development is the study of the growth and maturation of newborn infants in the first few weeks of life. This research area focuses on physical, cognitive, and emotional development during this crucial period. Researchers in this field investigate factors that influence neonatal development, such as genetics, environment, nutrition, and medical interventions. Understanding neonatal development is important for identifying risk factors for developmental delays and designing interventions to support healthy growth and development in newborns.
