COLOSTRUM Colostrum is the first stage of breast milk that develops during pregnancy and lasts for a few days after the birth of the baby. It is also much thicker than the milk that is produced later in breastfeeding. Colostrum is high in protein, fat-soluble vitamins, minerals and immunoglobulins . Immunoglobulins are antibodies that pass from the mother to the baby and provide protection for the baby from a wide variety of bacterial and viral illnesses. Colostrum will be replaced by transitional milk 2 to 4 days after birth.

Facts about colostrum:

• Commonly called “Liquid Gold” • Can be yellow to clear in color • Beneficial in loosening mucus in baby • Easily digested • Serves as a laxative and helps clear the baby’s intestinal tract • Very high in protein • Contains antibodies which help the baby fight infection • Coats the stomach and intestines and protects against any invading organisms

TRANSITIONAL MILK Transitional milk occurs after colostrum, and you will find your milk changing character and increasing in quantity. When you pump or breastfeed regularly, your breasts will be stimulated to produce transitional milk. The content of this milk includes high levels of fat, lactose and water-soluble vitamins. This milk contains more calories than colostrum and is very high in protein content.

MATURE MILK Mature milk begins to appear near the end of the 2nd week after the baby is born. It may take longer depending on when breastfeeding or pumping was initiated. Mature milk is mostly water, which is necessary to maintain correct fluid balance for the infant. The rest is comprised of carbohydrates, proteins, and fats that are necessary for both growth and energy. It is also composed of wonderful immunologic properties. These properties do not disappear after colostrum, but remain throughout breastfeeding.
