Usually antibodies against A and B are IgM - they are too colossal to cross the placenta, but type O people occassionally produce an IgG antibody (called anti-A,B). This is the antibody that usually does the destroy.
The baby have a chance for one type O (between 0 and 25%), and in that bag there's no problem. However, there's a 75 to 100% chance that the babe-in-arms will be type A, so there could be a problem.
The likelihood of a type O mother's immune system attacking her baby's blood because of this anti-A,B antibody are rare, but contained by cases were a womanly is type O (especially if she's Rh positve), it is investigated along with other possible cause.
It is exceptionally rare although some cases own been reported. The usual nouns is the Rh factor.if the father is Rh+ and the mother Rh- there is a conveyance of E-F after at least one pregnancy next to an Rh+ fetus. This is because the mother will develop antibodies to the protein which will cross the placenta in Rh+ children following the first and attack their RBCs. In group A blood type differences, the mother already have mature imperviousness to this blood type, but these antibodies do not usually cross the placenta. If she is Rh+ or you are both Rh-, you really have nought to worry something like.
not enough info. what is the Rh status of respectively parent?
even w/o this info, chances are small. 85% of race are Rh+, so mama won't be killin baby, and it's adjectives good within the hood.
