Anne-
How about some sage tea if there is a true oversupply?  I am also a
little concerned that all of the milk that has been expressed is
foremilk.  It sounds like the breasts are not being truly emptied and
therefore little hind milk is being expressed.  She might try fewer but
longer pumping sessions to get a more balanced milk.
