Will a man with AB blood type and a woman with O blood type have a child with hemolytic disease?

Patient's question:

Problem Description: I heard that the risk of my child developing hemolytic disease is relatively high with my husband's blood type. How can I avoid this? Thank you

Doctor's answer:

Hello, this situation is relatively easy to cause hemolysis, of course, hemolysis caused by ABO blood type incompatibility is generally not too serious.
