During any pregnancy a small amount of the baby's blood can enter the mother's circulation. If the mother is Rh negative and the baby is Rh positive, the mother produces antibodies (including IgG) against the Rhesus D antigen on her baby's red blood cells.
If the baby is born with AA or AO, that is type A blood. If the baby is born with OO, that is type O blood.   As for the Rh, that is the luck of the draw. The baby may inherit the negative from the mother or the positive from the father. More likely it will be Rh positive, but there is a chance that it would be negative.
