I wish I could address all of the questions you raise, Barbara. I am sure there
is someone who could. I guess, I am just not so friendly to these Ultrasound
studies because they are used by many to justify use of the Playtex Nurser as a
"preferred feeding method" for breastfeeders. My experience, and that of many
others is, that this particular nipple causes shallow sucking and makes it quite
difficult to move a baby back to breast.

Nuk is not my favorite nipple either, though I've found it helpful in babies
with a tight, biting latch. Chele Marmet seems fond of using it upside down.

A central groove in the tongue is not the only component of effective
breastfeeding....and I think Smith would agree here. The problem is that the
Smith's research is being used by OT/PT people to convince us that it is.

I am sorry if I came off as judgemental and overbearing. Perhaps I shouldn't
have said the information was outdated as much as overused and not supported
anecdotally.

Sometimes just because something is logical doesn't mean it works.
