Erythroblastosis foetalis is a special condition of Rh incompatibility observed when the mother is Rh-ve and foetus is Rh+ve.

• During first pregnancy: When the first Rh+ve infant is born to the Rh-ve mother, some of the RBCs of the foetus may enter the mother’s body during delivery. This results in the formation of Rh antibodies in the mother’s blood.
• During second pregnancy: If second child of the mother is also Rh+ve, the Rh antibodies present in the mother’s blood may attack and destroy the RBCs of the second child.
