Infant sleep research focuses on studying the sleep patterns, behaviors, and needs of newborns and young infants. This area of research aims to understand factors that influence infant sleep, such as parental behavior, environment, and development. Researchers also investigate the impact of sleep patterns on infant health, development, and well-being. Studies in this field may involve measuring sleep patterns through monitoring devices, conducting surveys or interviews with parents, and observing infant sleep behavior in controlled settings. Ultimately, the goal of infant sleep research is to improve our understanding of sleep in early infancy and to promote healthy sleep habits for infants.
