Preterm Infants
Infants born prematurely will have their skin, sebum, microbiota, blood, and mother's breast milk analyzed for changes between 0, 2, and 4 weeks of life.
|
|
Term Infants, Control
Term infants enrolled in the UC Davis Lactation Study (protocol # 216198) will serve as the control group for this study; they will have their skin, sebum, microbiota, and mother's breast milk analyzed for changes between 0, 2, and 4 weeks of life.
