My mother gave me wool fat you get it from a chemist in a brown glass container. it works for crack nipples,sore breasts and it doesnt affect the baby feeding when he or she comes along too.i just took deep breaths up till then and stayed away from crying babies they make them ache(that bloomin let down who invented that ahh). hope you get relief soon.

Warm compresses are also good...wet a washcloth and microwave it for 1 minute. Put it on and it may help.

Now if the soreness is w/the nipple area, I used a cream called Lansinoh (purple tube) and that helped with the soreness and I didn't have any of the cracking. I used it before delivering and after when nursing.

Good luck and know that it's all worth it!
