Came across this when reading unrelated material:

"Whenever a new discovery is reported to the scientific world, they say first,
'It is probably not true.'  Thereafter, when the truth of the new proposition
has been demonstrated beyond question, they say, 'Yes, it may be true, but it
is not important.'  Finally, when suffiecient time has elapsed to fully
evidence its importance, they say, 'Yes, surely it is important, but it is no
longer new.' "

                                                                                                -Michel de Montaigne (1533 - 1592)


I believe that breastfeeding information is in stage 2 of this quote.
