  27. BREAST MILK • INFANT WITH GROWTH RATE AT 95%ILE BUT • MOTHER’S MILK PRODUCTION IS ON THE 5%ILE • WEIGHT GAIN <5%ILE = RED FLAG FOR UNDERNUTTION • MISMATCH IN MACRO AND MICRO NUTRIENTS

  28. BREAST MILK • ADVANTAGES OTHER THAN NUTRITIONAL • CLEAN MILK • PROTECT AGAINST INFECTION • MACROPHAGES • LYMPHOCYTES • LACTOFERRIN • LYSOZYMES • IgA
