Caring for a child with haemophilia

Haemophilia is an inherited bleeding disorder in which the blood fails to clot normally. People with haemophilia lack the normal levels of clotting factors, particular proteins that are necessary to the blood clotting mechanism. Haemophilia A (classical Haemophilia), the more common type of haemophilia, is due to a deficiency of factor VIII (factor 8). Haemophilia B (Christmas Disease) is caused by a deficiency in factor IX (factor 9).
