I have been told that I may leak a bit of milk from my breasts at the end of pregnancy. She is a Board Certified Lactation Consultant, as well as a retired La Leche League Leader. Your body will produce colostrum for your new baby during her first three to four days of life, transitioning into mature milk by the time she is about two weeks old. Typically around the fourth or fifth month of pregnancy a woman's breasts begin to produce colostrum, in preparation for the birth of their baby.
Some mothers do notice that colostrum is present much earlier in their pregnancy.
It's important to remember that breast changes do not occur at the same time for every pregnant woman.
