Thanks, Jane.  I appreciate your kind words about Breastfeeding Made 
Simple.  Funny you should mention the "Magic Number."  My article 
explaining this concept and how to use it with mothers just appeared in 
the second issue of Clinical Lactation, the last issue of this new USLCA 
journal that is open access.  You can read it at:

> In my experience, the hospital-grade pumps remove a greater percentage of milk than a "work" or "convenience" pump.  At a conference I attended once, the researchers showed that a  healthy nursing baby removes about 75% of available milk over a 24 hour period and with each mer, less milk is ejected and greater percentage of milk removed.  If a pump does not stimulate enough milk ejections to remove at least 75% of the available milk, then supply will drop.  I think everyone should read Nancy Morbacher's simple explanation of milk supply and volume control in the book Breastfeeding Made Simple.  The problem with most moms who are exclusively pumping for whatever reason is they don't have an understanding of what Nancy calls their Magic Milk Number.  An inefficient pump combined with insufficient frequency can cause loss of milk supply.  An efficient pump used infrequently can cause a loss of milk supply.  An inefficient pump used VERY frequently (more than most moms are willing to do) may NOT cause a loss of supply.  The problem is we don't have breast pumps that can sense the frequency and efficiency the breast needs in order to maintain supply.  When we invent a sensor that signals the pump to jump on the breasts and elicit MER and continue until milk is drained with little effort for mom, we will make millions.  But wait!!!!  There is such a thing!!  And it only costs about half a million dollars over the course of 21 years.  It's called a baby!
