Breastfeeding

Lindsay • Atlanta
My lil guy is 5 days old and I'm breastfeeding. He has jaundice so we have about two rough days feeding and they gave him a pacifier so now he bites down on me. 
One nipple has a blister and the other is so sore it's cracked. 
I honestly don't know if I can do this! It hurts so badly, I cringe when he needs to feed BC it is so painful- esp at first. 
Anyone else having the same issues? What should I do?
