<<4) they have MIS-information, like (in
reference to inverted nipples) "A breast shield, a dome-shaped plastic shield
with air-flow holes, may also have to be worn when feeding to help the baby
latch on." Are they talking shells or nipple shields?? >>

According to the Breastfeeding Answer Book as well as the Womanly Art of
Breastfeeding, breast shells are also called breast shields (for treatment of
inverted or flat nipples) , but not to be confused with nipples shields.

Lisa Jones, LLLL in Wellington, south Florida, USA, just west of Palm Beach-
who answers way too many questions about so-called "flat nipples" or "inverted
nipples"  even if they are neither really flat nor inverted but somehow Mom is
convinced that she is inadequate for breastfeeding.
