Effect of Increased Enteral Protein on Body Composition of Preterm Infants

Qualifying participants will be randomly assigned to receive either standard protein supplementation (control group) or high protein supplementation (intervention group). Intervention group: A fixed amount of commercially available hydrolyzed bovine protein will be added to fortified human milk after establishment of full enteral feeding. Control group: Hydrolyzed bovine protein will not be added to fortified human milk after establishment of full enteral feeding. If parent agrees, stool "dirty" diapers will be collected 2 times (at the time of hospital discharge and at 3 months of corrected age).
