Three-hourly feeding intervals are associated with faster advancement in very preterm infants.

Objective: To compare the effect of two-hourly (Q2H) vs. three-hourly (Q3H) feeding on time to achieve full enteral feeding, growth metrics and respiratory tolerance in very preterm infants with birth weight ≤ 1250 g.

Study Design: Retrospective study review of 18 months before and after a change in our feeding guideline from Q3H to Q2H feedings.
