To add a comment to the discussion on the number of ounces babies intake:

We all know how we explain to moms that the milk at the end of a feed, ie
the hindmilk, has a higher fat concentration than the milk at the beginning
of the feed, and the wonderful word picture of the baby getting appetizers,
soup course, salad, main meal, then DESSERT!  The hypothesis being that the
rise in fat content ( and the corresponding hormonal response in the baby)
may be the signal that the meal is over--

Since expressed breastmilk is all mixed together, maybe the baby is really
waiting for the increase in fat content in order to signal satiety?  How
about a research project with "x" number of ounces in a bottle with another
feed being "x minus one ounces plus one ounce of separated hind milk".  See
if the baby who takes the regular amount of ounces still wants more, but
the baby who got the last ounce of separated hindmilk acts more satisfied.
If it worked, it could be a logistical nightmare for moms who are pumping,
but don't we all get the calls from the back to work 3-4-5 month olds who
can't keep up with the perceived need for more milk?
