Hi Shirley...I wonder if the babies you're talking about are
tongue-suckers?  Do you or the parents notice baby sucking on her tongue
or making "little piggy sounds" (air being forced through the nose by
tongue on the roof of baby's mouth)?  These are the ones I'll see try to
latch, suck 3-4 times, let go and look at Mom or start head shaking as
if lookin for the nipple.  Very frustrating!  My best response has come
from teaching finger-suck training as described in the BAB.  I encourage
Mom to get baby positioned comfortably, initiate finger suck training
for approx. 30+ sucks, then gently remove the finger and offer the
breast with a bit of colostrum hand-expressed on the nipple.

  Occasionally,if these babies  stay improperly latched their suck can
take the skin off the end of Mom's nipple in a matter of feedings.  At
that point, a nipple shield may be a useful tool in keeping baby's
tongue down and protecting the nipple from further trauma.
