Standard of care arm: Mothers will consent to providing DHM (if qualifies per hospital policy) or formula if MOM is not available. Infants are only eligible to receive donor milk only if 1) MOM is not available 2) if infant initiates feeds before day 3 of age. The donor milk feed would be stopped on day 5 of age.

Mothers will consent to providing DHM if MOM is not available. If the infant reaches 100 ml/kg/day of feeds (one feed advancement prior to full feeds) and MOM remains unavailable, they will transition to formula in preparation for discharge. Infants cannot be discharged on donor milk.
