I know that if a mother has Rh neg. and her baby has Rh pos., it causes incompatibility. But I don't get it since the Rh pos can receive both Rh pos and Rh neg. So the baby should be fine. Shouldn't it be the other way around?

Wouldn't the baby, if Rh neg not be able to function properly if the mother's Rh pos gets in its blood, which is bound to happen if they share an umbilical cord...

All of the above answers are correct. However, the real problem isnt with the first pregancy, unless there is placental bleeding. But with the subsequent pregnancies because after the mother developes antibodies to the first baby during the birth, her new antibodies will try to attack the next babies. So that's why they will give you Rhogam, so that your body does not build up the antibodies.

The women w/ Rh neg. are lacking something in their blood that Rh pos. people have. With an Rh neg. it's like the baby is trying to add something to the mothers blood, so the mother's body rejects it. Rh pos. people don't have to worry about it because they already have this substance in their blood. The baby can't add or subtract anything from their blood. Is that too confusing? I hope not...that's the simplest way I can explain it.

if the rh neg mother has the rh pos baby her immune system will recognize it as foreign and attack it. if the mother is rh pos and the baby is neg then there is simply not an extra protein for the immune system to attack.
