Hey netters, Let me throw this into the equation regarding a drop in BM
supply at 4 months.  As Per, Counseling the Nursing Mother, By Judith
Lauwers and Candace Woessner, Page 136, "The the milk yield of a
well-nourished woman will rise steadly from birth to six months and then
begin to decline slowly."  Here are their average yields of breast milk.
.
 Month Postpartum                 Volume(oz/day)
        0                               20.3
        1                               26.5
        2                               28.4
        6                               27.8
        6-12                            18.6
        12-24                           15.2

So, what is the norm, or is there one? If there is a drop at the 4 month
mark for what ever reason, It is not really reflected in the above info.
