> Because her blood and the blood of the baby mix, she carries cells from the baby for many years afterwards.
This is not true. If the baby had AB blood and the mother had A, then the baby's blood cells would be attacked by the mother's.
It does happen. https://en.wikipedia.org/wiki/Hemolytic_disease_of_the_newbo...
I don't know about cells of the baby remaining in the body of the mother, but in the link you posted it says that HDN is caused (a) in the baby (b) by IgG antibodies (not cells).
