According to a joint statement by the World Health Organization (WHO) and United Nations Children's Fund (UNICEF): "The best food for a baby who cannot be breastfed is milk expressed from the mother's breast or from another healthy mother. The best food for any baby whose own mother's milk is not available is the breastmilk of another healthy mother" (UNICEF, p. 48). "Where it is not possible for the biological mother to breast feed, the first alternative, if available, should be the use of human milk from other sources. Human milk banks should be made available in appropriate situations" (Wight, 2001).
