Participant Flow

Eligible study participants included premature inborn infants at \<1500 g BW with no barriers to enteral milk feeding. Infants were approached and enrolled within the first 72 hr of life.

Of 223 inborn infants \<1500 g BW between September 2015 to August 2016, 33 infants were excluded, 59 could not be enrolled within 72 h, and 6 were not enrolled because their parents declined. Of the 125 enrolled infants, 8 were removed from the study owing to GI defects or complications unknown at time of enrollment that precluded enteral feeding.

Measure
Infants Fed Mother's Own Milk
Infants fed \>50% mother's own milk with enteral feeding. Observational - no intervention: This study will observe cohorts of infants who are fed primarily either their own mother's milk or donor milk as part of their routine care. No direct intervention is performed as part of the study.
Donor Milk Fed Infants
Infants fed \<50% mother's own milk (and thus \>50% donor human milk) with enteral feeding. Observational - no intervention: This study will observe cohorts of infants who are fed primarily either their own mother's milk or donor milk as part of their routine care. No direct intervention is performed as part of the study.
