I am a bit behind in posts but this has been on the market in the U.K
for a number of years. If memory serves me right it was originally
intended for cosmetic use for inverted nipples. Someone obviously
realised that there was another market - breastfeeding. It was sold for
this purpose after very little research, about 9 women I think and not
all of them had delivered when it was marketed. The research was
abysmal. It is expensive here and I have only come across a few women
using it, however I do know a few people in the breastfeeding field
recommend it. I am not one of them.
