This comprehensive 4-hour course explores the life-saving benefits of donor human milk for premature and ill infants. It examines the history and current state of milk banking worldwide, comparing the safety and regulations of pasteurised milk banks with informal milk-sharing practices. Donor human milk provides significant health benefits for infants who are unable to chestfeed or bodyfeed, making it a crucial resource for vulnerable newborns. Milk banks ensure the safety and quality of pasteurised donor milk through rigorous screening and processing. In contrast, milk sharing remains unregulated and lacks consistent safety assurances. Ongoing research continues to refine milk banking practices and improve accessibility, yet barriers such as time constraints and lack of awareness persist. Encouraging milk donation is essential in supporting infants in need and ensuring equitable access to human milk.
