This makes me think of the Widstrom et al video, Baby's Choice, which as I
remember shows a newborn's first efforts at the breast as a random-looking
grab at the nipple, then transferring fist to mouth.  The grabbing was part
of the crawling motion that moved the baby closer to the nipple.  I had
thought of it as also transferring scent/taste from nipple to mouth.  Or
could it be the other way around - a transfer of amniotic fluid scent to
the nipple??
