Early Total Enteral Feeding Versus Convention Enteral Feeding in Preterm Infants 27-32 Weeks of Gestation

Enrolled participants will be randomly assigned to one of two study groups: 1) early total enteral feeding (ETEF) or 2) conventional enteral feeding (CEF). Regardless of study group assignment, mother's own breast milk (MOM) is the feed of choice and donor human milk is being offered if the MOM is not enough to complete the intervention as assigned Intervention group: Feeds will be initiated with a target volume of 80 ml/kg/day starting within the first two hours after birth. Volumes will increased by 20 ml/kg/day till day 4 (total 140 ml/kg/d) and then 150ml/kg/day on day 5. Control group: This group will receive enteral feeding volumes at a rate of 20 ml/kg/day starting within the first two hours after birth and rest of the daily requirement as Total parenteral nutrition. Volumes will be increased by 20 ml/kg/day till day 3 and thereafter by 30 ml/kg/d till 150ml/kg/day on day 6.
