I don't think the size of nipples determines if you can breastfeed. Mine used to be small and they grew with my first and never really went back to normal.
My sister has inverted nipples (I know weird). She had to use a nipple shield at first until the baby's mouth was bigger. She breastfeed all 3 of her kids. It is possible.
^^^same here with DDs I breastfed my first for over 5 months. It is possible! I used a nipple shield which they provided at the hospital when I delivered. But you can also buy them at like target and other stores. I'm also planning on breastfeeding this baby as well, and you might be able to do it without the nipple shield, but if you can't don't be discouraged! You can see a lactation consultant in the hospital usually after you deliver. I know the hospital I was at was very adamant on helping me get it right! Good luck
I shall admit I too have what they call "hershey kiss" nipples, they are not big at all and im in a D cup /.\ im still gonna try brweastfeeding tho!
