Hi all,

I too have seen sudden drops in milk supply with the minipills are started.
For example, an experienced mom four months into pumping at work, dropped to
30% of former volume within one week of starting them. I haven't seen any
data about who is at risk, when, or why, but I have a theory.

We know that prolactin's influence on milk synthesis declines and by 3-4
months is a fairly insignificant factor. We know that progesterone inhibits
prolactin. My guess is that supply drops with minipills when mom still needs
the prolactin boost from pumping or breastfeeding to maintain supply, either
(1) because she is in the earlier postpartum period, rather than further out,
and/or (2) her milk synthesis capacity is at the edge of acceptable ranges
and she needs absolutely everything to be right.  Maybe there are other
factors too - this makes some scientific sense to me.

THAT it happens - I believe completely. Why it happens - I don't yet have an
expanation. Anyone have further ideas?
