Jeannette's experience is similar to one I had.  A mom who is pumping for a
friend gets 3 1/2 oz or so from one side, only 1/2 oz from the other.  When
I asked if her baby prefers the higher yield side, she said he not only has
no preference, she hears equal swallowing on both sides.  Out of curiosity,
I had her try the glass shield.  On the high pumping yield side, the glass
shield hurt.  On the low pumping yield side, it was a little uncomfortable,
but milk began flowing at a higher than usual rate.  She lost interest
before I did, but I think the shield would certainly improve her yield on
that side, if not bring it up to the other side.  Yet her baby, over 9
pounds at birth, has always done well on both sides.
