Medela  pump kits available in my hospital are packaged sterile.  I feel
comfortable using them with no further innitial treatment.  Those
available in my community (purchased outside of hospital) are packaged
as "clean".  It is difficult as a practitioner outside of hospital to
obtain the sterile kits and they are more expenisve.  In the case of the
"clean" kit, I feel the instructions to boil first are best followed.
In the case of the sterile kit I feel perfectly comfortable telling the
mom the innitial boiling step called for in the instructions can be
disregarded.  Note the same instruction manual comes in both types of
kit packages.
