13 January 2011	New search has been performed	This updates the review "Delayed introduction of progressive enteral feeds to prevent necrotising enterocolitis in very low birth weight infants" published in the Cochrane Database of Systematic Reviews, Issue 2, 2008 (Bombell 2008). Updated search includes three new trials (Ostertag 1986; Karagianni 2010; Leaf 2012). New authorship for this review update.
13 January 2011	New citation required and conclusions have changed	The addition of new trial data has increased the total number of participating infants to 600 and modified the implications for practice and research.
2 February 2008	New search has been performed	This updates the review "Early versus delayed initiation of progressive enteral feedings for parenterally fed low birth weight or preterm infants" published in the Cochrane Database of Systematic Reviews, Issue 1, 2000 (Kennedy 2000). The title has been changed to "Delayed introduction of progressive enteral feeds to prevent necrotising enterocolitis in very low birth weight infants" and has a new authorship of Sarah Bombell and William McGuire. Changes made to the original protocol are outlined below: 1. Introduction of progressive enteral feeds is defined as feed volumes more than 24 ml/kg/day (1 ml/kg/hour). 2. The population has been restricted to very low birth weight and very preterm infants 3. Subgroup analyses of extremely low birth weight and extremely preterm infants, and infants with evidence of intrauterine growth restriction or absent or reversed end‐diastolic flow velocities in Doppler studies of the fetal aorta or umbilical artery were prespecified. Search updated December 2007. No new trials were included, but one on‐going trial was identified. The findings and implications for practice and research of the review have not changed overall.
