 In this study, 17 NICHD Neonatal Research Network sites will enroll approximately 96 infants at 12-72 hours of age. Enrolled infants will be randomly assigned to receive either 10mgkg of 5 inositol, 40 mgkg of 5 inositol, 80 mgkg of 5 inositol, or 5 glucose given in the same volumes and timings as the inositol dosage to maintain masking. Inositol will be administered intravenously until babies are feeding normally, at which time the same dose and formulation will be administered enterally orally or via feeding tube. Concentrations of inositol will be measured in blood, urine, and milk received.
