There are literally dozens of blood factors that make our blood unique. The ABO and Rh systems are merely the most important. Anti-C antibodies are a part of the CDE system, and have the potential to cause mild to moderate hemolytic disease. I am not familiar with anti-B antibodies, nor could I find any mention of them in a quick perusal of the standard texts.

The issue is whether or not the baby has C antigen or not. If the baby does not have C antigen, then there is no problem. If the baby does have C antigen in its blood, then there is a possibility that your antibodies could begin to attack the baby's blood, destroying the blood to a greater or lesser extent, leaving the baby anemic to a greater or lesser degree. Close monitoring will be essential, as it is possible to treat this condition successfully, if the baby is effected.
