The mother’s blood does not normally mix with the baby’s blood during the pregnancy, unless there has been a procedure (such as amniocentesis or chorionic villus sampling) or vaginal bleeding. During delivery, however, there is a good chance that some of the baby’s blood cells will enter the mother’s bloodstream.
