Medical Blood antigens -- pregnant mothers' blood types and infants' blood types

[mktsgm]

I have a small question regarding pregnant mother's blood types and infant's blood types.

We all know the if an Rh-ve mother carries an Rh+ve child, there is a possibility that their blood may mix during the delivery.

This may induce some (Rh D) antibodies in maternal blood. In case the same mother happens to carry another Rh+ve child for the second pregnancy, the antibodies of the mother will create a lot of problems to both.

My doubt here is, say if the mother is B+ve and the child is A+ve, the same situation arises with respect to A,B,O antigens. Why this antigen/antibody axis does not create problem in pregnancy?

Apparently it does.

What leads you to believe otherwise?

Oh. Thank you very much.

But if so why we aren't much bothered about ABO compatibility of the parents? Even if screened, the parents are not generally told about this fact. Perhaps not to scare them...

We seem to insist only on the Rh type excessively...

Anyway thanks.
