Several of you have requested details of this study so will respond to all.
 I was vague in my original note as, although I had seen copy of page in
study detailing cost savings, was not an official recipient.  Have contacted
the woman who introduced me to the study to confirm the info is for general
consumption (she is using it to help justify hiring LCs at the clinic for
which she works).  She had no problem with providing the following info:

Kaiser Permanente
Internal Feasibility Study of Lactation Programs and Their Potential Outcomes
by Christine Hoey, RN
Durham NC
Population studied in Raleigh, Durham and Charlotte

Do not know if study is yet published but copy states it is intended for
publication. Despite the fact that my friend's copy does not even hint at a
need for confidentiality,  I suggest that any of you who have a strong need
for this info go thru appropriate Kaiser channels for details and permission
to use them.

Perhaps also useful is "Difference in morbidity between breast- and
bottle-fed babies." Kathryn G. Dewey.  Jnl of Pediatrics 95, 126:696-702

RE: recent question re switching from volunteer to paid LC
I too had this concern when was a very active volunteer for Nursing Mothers
Counsel before becoming IBCLC. NMC policy is must switch immediately to
affiliate status -- can advise and teach volunteers, etc. but may not take
contacts due to conflict of interest.  Of course I still get occasional calls
so, with permission of local chapter coordinator, warn them up front of my
changed status but do provide free phone counseling.  If home visit needed
refer them to active volunteers.

Mothers referred to me since my change of status are VERY DIFFERENT from
those I saw as volunteer.  My experience over last year has been that if they
have to pay for it they have exhausted all other options for advice first and
are coming to me on the assumption that IBCLC means I have more to offer.
 Very occasionally someone calls who doesn't need this level of fire-power
and I do refer them to volunteer resources.  Likewise, the local NMC
volunteers refer the moms they feel are beyond them to me.
This is comfortable to all.
