>physics of the sns, the milk comes
from the breast FIRST, whatever is there, and THEN from the sns.  This
has been an encouraging, reassuring fact for many mothers.        Anybody
out there care to explain/confirm this?
Hello Susan and Netters,
I try to use the analogy of the IV and a piggy-back IV.  Those not in the
medical field
let me try to explain.  An IV is hung high on a pole that solution flows
into mother's 
arm/vein.  A piggy-back antibiotic bag of solution is then attached to the
same IV
already running and hung at a higher level.  The flow is opened up so it
flows into the 
patients arm/vein at a faster flow than the larger IV.  After it is in, the
other IV will flow.  Of 
course then a nurse will open that IV up to the flow that Dr. ordered. 
Well, now imagine 
having the SNS secured on the breast and tube opened up.  Mother's let down
comes
and it will flow at a faster pace than the SNS flow.  Also as mother's milk
increases, that
milk will flow at a faster pace than the SNS flow.  That is how you know
when mother's milk
has increased.  (one of the ways).  She will complain that the baby is not
taking as much
milk from the SNS.  That is usually a good sign.  Hope that is helpful. 
Let me know if you
have any questions or concern.  Have a wonderful weekend.  Nice and sunny,
over 80, and 
we are heading out to" veg" out in a place secluded in trees and a lake for
the weekend.
