The CanDo (Canadian Donor Milk) Trial

The intervention will involve providing donor milk as required as a supplement to parent milk and will last for the duration of the infant's initial hospitalization. The intervention will continue throughout the hospitalization at any time that supplementation is recommended by the clinical team, and is expected to last from 0 to 72 hours post-birth. All donor milk will be aliquoted into individualized syringes in the Rogers Hixon Ontario Human Milk Bank which is located in Sinai Health. The decision regarding the timing and duration of the supplementation will be determined by the medical team in the well-baby unit based on the specific needs and circumstances of each mother-infant dyad. As this study follows a pragmatic approach, the clinical team will assess the need for supplementation based on the mother-infant dyad's condition.
