Inverted nipples are very common with women, and many women who have inverted nipples have a successful breastfeeding relationship with their baby. Have you checked out the Aust Breastfeeding Assoc website, or become a member with them? You'll find heaps of info on their website, and by becoming a member you'll have access to a wealth of support with lactation consultants and other breastfeeding mums.
What Jodi said

Plus, I know that nipple shields are a whole different kettle of fish now days. My eldest is 9 and I know that the ones they have now are far superior than the ones when she was a baby. There is also a device for inverted nipples which 'pulls' the nipple out just before feeding. I think you'll find with correct attatchment for inverted nipples, the sucking will drag the nipple out during a feed anyways (??).

Expressing feeds is a great idea if you cannot feed through the pain of inverted nipples. It makes sure that bubs gets what he/she deserves and needs from their milk.

Definately join the ABA and have a lactation consultant on hand. Unfortunately, many of the midwives you find in the hospital might not be of much help, many of them are all too keen to push artificial baby milk down a newborns throat, so be aware of this and try to resist it until you have seen a qualified lactation consultant.

Best of luck with your journey .
