Michelle,  Thank you for your reply!  I too have never seen any written data
on how much time it takes the stomach to signal the brain that it is full.
 But I have heard this for the past 15 or more years.  I agree that what
might apply to an adult does not necessarily apply to an infant.  In my
experience with infants being fed breastmilk (and even ABM) by bottle I have
seen the the babies over eat.  The nipples used are slow flow and feeding is
inturrupted periodically to burp and still the baby will take in far more
than his little walnut sized stomach should be able to hold.  They will drink
that bottle in 10 to 15 minutes and cry until given more. It is not
necessarily the person feeding the baby doing the coaxing but the baby
appearing to be hungry.  This is why I tend to think the "20 minute theory"
is quite possibly accurate.

I think that the actual nursing is what is possibly missed by the baby as
well as possibe "feeling" of hunger (maybe hunger for mom's presence!).
 Whether it be 10 minutes, 20 minutes or no minutes,  the baby is obviously
distressed.  We are such a food oriented society.  Whenever there is a
problem, a happy time, sad time... we eat! If we are sick, we are told to
eat.  If we are well, we are told to eat.  Babies are not treated
differently?

Just a thought.
