Early iron supplementation for iron deficiency in very preterm infants fed donor breast milk

The goal of this clinical trial is to determine the serum ferritin level and hematocrit level in very preterm infants receiving donor breast milk(DBM) with an early iron supplementation protocol . The main questions it aims to answer are: Does earlier iron supplementation provide increased ferritin levels at 14 and 28 days of life in subjects fed primarily donor breast milk?

Iron supplementation will be implemented when the infant achieves 80ml/kg/day of enteral feeds, as contrasted to the current protocol of full feeds (140 to 160ml/kg/day), the latter usually by Day 14 of life.

At day of life(DOL) 14 (± 4 days), a blood sample will be obtained for serum ferritin determination. Similarly, a second blood draw would be performed at day of life 28 (± 4 days) or prior to discharge, whichever comes earlier
