On this whole theme of babies who don't nurse.  Nipple confusion?  Impairment?
As with most things like this, it's not "either-or" so much as "both-and".  I
think one thing we can agree on is that when babies don't nurse, it's because
they can't make it work for them at that particular time.  This is what
parents need to know.  So often it feels to the mother that the baby is
"refusing" to nurse, doesn't like the breast, doesn't want it, doesn't like
her.  That the baby is "pushing it away".  I don't believe any newborn is
purposefully rejecting or pushing the breast away. It can be simple poor
positioning/awkwardness in presenting the breast; mouth and facial structures
temporarily impaired by birth trauma, meds, etc.; difficult mouth/breast fit;
"nipple confusion" after experiencing the "super-stimulus" of a bottle and
fast milk flow; or, in a few cases, true neurological impairment; or other
things everyone has mentioned.   Miriam
