Sunny California seems to be suffering from an epidemic of low milk supply moms. I am beginning to feel there is some physiological process happening that we have yet to document. Standard wisdom in the clinic I work at is that milk supply will be permanently impaired if breasts improperly stimulated in first 48-72 hours. But I see plenty of exceptions to this rule. (Why do some mothers respond to insufficient breast emptying with engorgement day 3 and others with delayed and low lactogenesis?) On the other hand I see moms who have no suspicious history, no birth trauma, no health issues and who have managed breastfeeding in a textbook fashion since hour 1 but make less than 10 oz q24h. No emotional issues either that I can determine. I, and others locally, are seeing enough of these women that we are going to attempt to document them more formally as a group. There simply are too many unexplained cases of low milk currently. Anybody else similarly frustrated? Or is it something in the water locally?! Joanna Koch, IBCLC in Los Altos, CA
