I need help ladies. any advice on sore nipples. boobs get engorged and he sometimes has a hard time latching right. it's getting to hard to bare sometimes and he has to be fed and I'm really trying to avoid formula for as long as I can. Don't have a pump at the moment to help express it from that boob. I've been rotating left or right breast at feedings so I can let one rest but damn it, it's still sore on its turn.
