If a baby’s and mother’s blood are incompatible, it can lead to fetal anemia, immune hydrops (erythroblastosis fetalis) and other complications. The most common type of blood type incompatibility is Rh disease (also known as Rh incompatibility). The Rh factor is a protein on the covering of red blood cells.
What blood types should not have babies together?
When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.
Can you have a different blood type than your mother?

Why does my baby have a different blood type than me?

Can a baby be born with a different blood type than the parents?
While a child could have the same blood type as one of his/her parents, it doesn’t always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B. These two types are definitely different than parents’ blood types!
What blood type kills babies?
Most people are Rh-positive. People without the protein are Rh-negative. You inherit your blood type from your mother and father. If a Rh-positive baby’s blood passes to its Rh-negative mother during pregnancy (or delivery), the mother’s body will attack the baby’s red blood cells.
Can O and A+ have babies?
