I disagree with Bonnie about moms being told to decrease pumping and
production.  I've seen happen over and over, after about a month in NICU and
big volume of milk due to pumping, mom has a decrease in the volume.  This
decrease is from several things: 1) she gets tired of pumping and slowly and
unconsciously goes from a very specific pumping schedule to a more loosely
followed schedule, or rather than every 2 1/2 to 3 hours, she stretches it
to 3 1/2 to 4 1/2 hours; 2) mom doesn't pay as much attention to rest, food,
fluids like she did right after the birth, and doesn't have the  support
that she had, sort of "your baby is in the hospital, still?  So get a life"
attitude from family and friends and employers; 3) the friendly nurse who
says "I don't think we'll ever be able to feed all your milk to the baby,
you just have soooooo much" which gently tells mom to cut back.  I
personally prefer to encourage her to keep her production high because these
happen almost every time.  I would NEVER tell a mom she's producing too much
milk!  Also, I think it was Dr Neifert  who spoke about a normal drop in
production at about 1 month.  I don't have a reference for that, but she
said it at a conference in Albuquerque several years ago and I believe there
is a reference.
