Infants who have problems with a blood type other than their mother's suffer from something called Erythroblastosis fetalis. This refers to two potentially disabling or fatal blood disorders in infants: Rh incompatibility disease and ABO incompatibility disease. Either disease may be apparent before birth and can cause fetal death in some cases. The disorder is caused by incompatibility between a mother's blood and her unborn baby's blood. Because of the incompatibility, the mother's immune system may launch an immune response against the baby's red blood cells. As a result, the baby's blood cells are destroyed, and the baby may suffer severe anemia (deficiency in red blood cells), brain damage, or death. Generally this condition is a problem during pregnancy and in the period immediately after delivery. It would be obvious at the time of delivery or within a day or two after delivery - depending on the severity of the disease. If your children were old enough for all of them to be together in a photograph then their cause of death would not be Erythroblastosis Fetalis. There could, however, be some other genetic condition that could cause death of a number of children in the same family. Vicky Drake dvicky@cox.net 1. RH blood factor (Barbara Young) 2.
