Colostrum
Initially there will not be any actual milk in the breast. Mother’s milk does not “come in” for two or three days or so after birth. Instead the breasts give out a clear sticky liquid called colostrums, which may vary a great deal in color-white, mustardy-yellow or gray- blue. It contains some protein and is nourishing. More important, however, colostrums are rich in the mother’s antibodies, and will give protection from many diseases in the first six months or so. This immunizing effect is lost if the baby is fed on fresh or dried cow’s milk during this time.
