The research that does exist relates to long term effects of silent
aspiration in adolescent, chronic silent aspirators who presented with
varying histories of cardiorespiratory problems.  One issue raised was
what came first, "the chicken or the egg" - chronic silent aspiration or
chronic CP issues.  Other studies suggests that EBM is "clear fluid"
which if so reduces risk and that natural immune factors are present.
However if you leave a bottle of EBM in a 98.5 environment, does it not
colonize?  And regardless of rate and breadth of this phenomena,
pulmonologists rarely even allow distilled water when the risk of
pernicious silent aspiration is present and what liquid could be more
"clear"?  So what you are advocating is, Well let's try it and see what
happens.  I wonder what would have happened had Einstein or Oppenheimer
said, "Gee, Let's just split this atom and see what happens?"

Recheck your resources, you'll find that to be inaccurate.  Studies that
I have seen did not break down formula -v- EBM.

Opps! What happened here?

You need to adjust your word wrap, most of your message is being
deleted.  The necrotic tissue was from pernicious silent aspiration.

infinity.  Flexor physiology is suckle physiology.  When infants suckle
the nipple is drawn fully to the oropharynx.  The oral phase is rendered
moot with the exception of expressing the milk.  Cup feeding engages the
oral cavity for processing the milk to be swallowed.  The undulation of
the tongue required to safely process liquid to the pharynx is not
developed pre 4 mo., it is after ATNR and extensor development is this
seen.  Milk is not lapped when drawn from a cup.  I have seen numerous
posts from LLL members who state the same.  It is drawn in by negative
pressure created by tongue pumping such as a piston draws air and gas.
Liquid bolus is not controlled in the transition between oral phase to
pharyngeal phase of swallow (ever seen a video swallow on an infant?, I
assure that this last statement to be true - me and a few researchers

Does not prove a thing when it comes to safe swallow.

13 years exp. feeding swallowing, 80 hours CE numerous video studies I
can't count.

None.

Read my posts again, I don't believe I said *aren't capable*  If I did,
I retract it.

My apologies if I appear as dogmatic or *negative*.

I feel stongly about posing a risk to those I manage when a small
segment adamantly insist cup feeding works when they miss one all
important health risk - aspiration.

Back atcha!

 A man comes upon a thousand dollars. He wants to surprise his wife with
the money, so he goes to the river, splits the money into ten jars and
floats them downstream.  Problem is the river divides before it gets to
his house.  How many jars does he average if he were to repeat this
process 10 times?

I have not nor will I criticize cup feeding EBM.  I am very anxious
(good and bad) to try it.  I need what I consider in my professional
opinion some fundamental issues addressed.  I am pursuing these ends
within the strengths and the limitations of my profession.  I want to
thank all who answered my posts.  My e-mail box was never this full.
Not even spam :-)
