Miriam Levitt wants to know if low milk supply is a result of blood loss.
Yes.  This is noted in the literature (check the Archives.  I think we've
discussed this thread before.  I think I and others have previously posted
with specific refs.  There was a good one in the journal, Birth, sev. yrs
ago linking low milk supply with anemia, as well.)

I have a client I  assisted with babies #1 and 2.  Baby #2 born last Fall --
very difficult labor with lots of blood loss. My client was  flattened after
the experience both emotionally and physically. Her milk supply was
depressed, breasts very soft, no evidence of lactogenesis II. I told her
that I felt her milk would come in as she recovered.  I thought was there
was a good chance for her  as long as she continued to nurse and do some
pumping since baby was frustrated by no milk and wouldn't suck long. This
Mom needed to use some formula as baby was losing weight.  She was too wiped
out to mess with SNS and take care of baby and 20 mo old.  She had good
family help, and they bottle fed, then handed baby to mother who tended and
slept with baby in the bed.  The mother used breast as pacifier to keep baby
interested in being at breast.  Over about a month's time, the milk supply
gradually improved.  She began to taper the formula.  Baby was pretty
willing to nurse -- esp. as the milk reward became quicker. By about 8 weeks
she was exclusively breastfeeding.  I recently had a contact with this mom,
whom I referred to a Traeger massage therapist for some body work.  The
therapist described  this woman as still seeming "fragile".  I think it is
good to reassure such women that they probably will recover and make milk,
but be reasonable about the fact that the healing takes time. They need an
excellent diet, lots of rest, and good support.  I think they also need to
talk to someone about how frightened they were by the experience. My client
was quite sure she was going to die.

I have also seen a mother delivered of twins who had lost so much blood that
she may have experienced a partial pituitary infarction.  She never
recovered any milk supply in spite of good efforts pumping and putting
infants to breast.

Hope this helps.
