There is no substance that can come close to human milk. Infant formula, a synthetic human milk substitute, is not a healthy alternative to mother’s milk. Formula is missing over 400 ingredients present in human milk, which cannot be duplicated by scientists in a laboratory. Every species produces milk designed specifically for its offspring. In addition to living white blood cells, human milk contains immunoglobulins (antibodies) which protect infants against illness. The protein in human milk is easily digestible, unlike the protein in cow’s milk, the base of most infant formulas, which forms tough rubbery curds in a baby’s tummy. A mother’s milk contains all of the nutrients her baby needs to grow and develop properly, and changes from minute to minute, hour to hour, and month to month to meet a baby’s changing needs. Human milk substitutes are static. They do not change in nutritional content to suit a baby’s needs at each particular stage in his life, nor do they contain protective antibodies or living white blood cells to help infants fight infectious disease (La Leche League International, 1991).
