>> "Breastfeeding and Human Lactation" by Riordan and Auerbach says that it
is the pump that stimulates the highest prolactin levels and the highest
milk volume for mothers. <<

Before accepting this statement at face value, you might want to research
what it was based on. I have seen a purported copy of a study which compared
an electric WR pump to a manual pump made by one of the other major
companies, ending with the conclusion that the WR pump caused higher
prolactin surges. If that's the total basis of such a claim, it's like
testing a car against a horse and buggy, and then making a blanket claim
that XXX car has the best ride. *Compared to WHAT?*

If there is more substantial proof than the study I remember, I'd be
interested in seeing it.
