Abstract
While direct at-the-breast feeding is biologically optimal, Neonatal Intensive Care Unit (NICU) admission due to infant immaturity or illness often necessitates the expression and storage of parent's milk. The provision of freshly expressed (never stored) parent's own milk to preterm infants is not widely prioritized, and this article provides an exploration of NICU practices and their implications for feeding premature or ill infants with parent's own milk. In this article, we discuss the potential biological benefits of fresh parent's own milk, highlighting its dynamic components and the changes incurred during storage. Research suggests that fresh milk may offer health advantages over stored milk. The authors advocate for further research, emphasizing the need for standardized definitions. Research is needed on the biological impact of fresh milk, both short- and long-term, as well as defining and understanding healthcare economics when using fresh milk.
