It is conceivable that some of the antibodies the mother is producing
would pass over to the baby *during pregnancy* and might temporarily
cause hemolysis in the baby.  This would be temporary, but may result in
unnecessary delay in breastfeeding, concern, possibly, about jaundice.

The prednisone itself is not a problem.  The mother will not pass on
antibodies in her milk.  This latter question has come up frequently on
Lactnet in the pass few months.  Repeat: *The mother will not pass on
antibodies in her milk*.
