Margery writes of baby post-frenotomy who is still having trouble extending
the tongue.  I think it sounds as if you are proceeding appropriately --
esp. with trading in the Nuk nipple (which promotes a kind of mashing
movement rather than a good draw-and-press.)  Using the Haberman is a good
idea.  You might want to suggest mom use a long, more firm pacifier since
she is determined to use one.  This would help baby pattern tongue more
appropriately.  The tongue is a muscle, and perhaps has more 'exercising' to
do post-clipping to tone up.  Also, I would suggest you make sure the nipple
shield you are using is the newborn,small size.  I seldom use the larger
size one unless mom has a huge nipple.  The large size shields have so much
room in them for baby to have to create vacuum and draw up tissue.  With a
great milk supply, a few days on small size shield ought to help this baby
use tongue better, all the while experiencing familiar sensations imprinted
on with other teats, and getting milk reward.  Weaning off to just breast
can then be initiated.  I often see clipped babies who really need time to
get the tongue strong.

BTW, my recent visit to relatives was sad.  My new niece has a very tight
frenulum, which was assessed on post-partum RN visit.  Pedi said they'll
clip at one yr, but breastfeeding "failed".  It is so hard when this happens
in one's own family.
