Following the NAMBA's (North American Milk Banking Association) guidelines
for expressed milk for hospitalized infants in my hospital we issue each
mother her own kit and instruct her to wash it in hot & soapy water, rinse
well, and air dry after each use.

We give her a new hospital basin (normally used for bed baths) to use as her
"sink".  Another hospital near here uses the original plastic package that
the kit comes in but I find that too small.   We tell her to continue to use
the basin at home, not to wash the pump parts with the normal dishes.

We give her containers of liquid castile soap to use in hospital and tell
her to use her normal liquid dishwashing soap once mother is home.

In hospital we are very short of horizontal space for air drying.   We clear
one drawer from her night table and leave it pulled out with a chux
(absorbent blue pad normally used to protect linen) folded absorbent side
out to air dry on.

NAMBA also recommends the milk be stored in sterile, hard plastic bottles
with sterile lids.   We have mom pump directly into new, sterile gradufeeds
every time.

The one step I am not quite happy with although so far it has not be
implicated in any baby problems is our lid solution.   We used to use
nipples, which was totally unacceptable.  Now we sterilize formula company's
ready to feed bottle lids in lots of 10 and instruct the mother to not touch
the inside of the package after opening.  If she pumps double sided one
package lasts less than 24 hours.  If she pumps single sided it is just
slightly over a day before she opens a new kit
