The overarching study aim is to evaluate the development of sleep behavior and gut microbiota (GMB), and their potential interaction, during the vulnerable period of the first year of life. Age-specific fecal profiles with bacterial genome sequencing will provide new insight into the functional coevolution of the GMB and host sleep behavior.
