Hi Netters,

I will try not to copy text, but just write my own stuff in and see what
happens.
 I was once told that you need to gently shake the milk to combine the
layer of cream that settles on top because vigorously shaking causes some
of the fat molecules to disperse out and therefore lose some.  That is why 
the Medela tearoff sheets on collection and storage have 
"gently"  writen in them.   Also,  when adding fresh milk to frozen milk,
make sure it has been refrigerated and that less amount is added to the
frozen milk.  I personally tell the moms that they can collect the milk
throughout the day in one container (or as many as they want) and then
freeze it all at night in appropriate size containers or  add small amounts
to the already frozen milk.  Remember the research Jan Barger and I did on
fresh milk at room temp. for 10 hrs. and minimal baceria counts.  Because
there is little research on storage and freezing of milk, I would not have
the mom add milk to frozen milk that is over 24hrs.   
Also, I do apologize for my jaundice post.   I did not mean to imply that I
did home phototherapy cases on 17mg bilis in the first  24hrs.  I would
work with the moms and babies in the hospital first with the SNS's (if Drs.
insisted on formula or water) and then biliwraps at home when the levels
began to drop..   Phototherapy lights are interesting.  There are pros and
cons with the high irradiance levels.  You can read that the higher the
irradiance level ( much over 12), the quicker the bili will decrease. 
Then, another source will say that there is a maximum theraputic level and
that anything greater than the max.  has no further effect.  I know in my
experience that if we could get mom's milk supply in quickly and maintain a
good supply, get the babies feeding frequently, stooling frequently
regardless if  it was an ABO incompatibility, cephalhematoma, or
physiological jaundice and keep the baby under continuous phototherapy that
the bilis would gradually go down.  Facinating field and I am sure we will
be learning more in the years to come.
Also, during pump trials, I would collect the pumped milk in the CSF bags
when possible and then give that milk to the mom to take home.  Other than
that, I would not liability wise give any milk collected in a trial pump to
a baby.   Enough for a sunday.  I am going swimming.
