My sister breastfed all through her second pregnancy. No problem with the nipples.
Oh god I have and my nipples were sooooo sore, it felt like hot needles going into them, I managed to breastfeed until I was 12 wks then couldnt handle it anymore, my 2yr old used to ask me if he was hurting me when he used to jump on as I used to scrunch up my face in pain :)
If your having pain in your nipples like shooting pain or pins and needles it could be a yeast infection in your breasts.
I've had a couple in the last 14M of breastfeeding. It's painful but with treatment clears right up
Call your Dr.
it's not yeast, I have already had my lactation consultant look at them. thanks everyone.
