This week several organizations, including the International Breast Milk Project, issued a call for human milk donations for infants in Haiti, as the U.S. Navy ship Comfort is equipped with a neonatal intensive care unit that can transport the breast milk. Yet, while nursing mothers have heeded the call, and some 500 ounces of donated breast milk have already been sent to Haiti by joint efforts of the International Breast Milk Project and the Human Milk Banking Association of North America, a joint statement issued by the World Health Organization, UNICEF and the United Nations World Food Programme suggests that, at this point, the necessary infrastructure isn’t yet in place for those well-meaning donations to truly make a difference. To learn more about the best way to help babies struggling to survive in the wake of the Haiti disaster, TIME spoke with Dr. Nune Mangasaryan, senior adviser on infant nutrition for UNICEF.
