help please!

any suggestions welcome. i'm pretty sure latching is ok but i suppose i could be wrong--i've been told by a midwife that my positioning and his latch is fine. yet i still have one nipple that bleeds--think it's cracked. please tell me your suggestions on how i can treat it! i've been pumping on the bleeding side and giving him the bottle of bm after he finishes on the other side because it doesn't hurt as much this way. want to go back to ebf'ing as soon as possible though.
Re: best way to treat bleeding nipple?
The only thing I found that worked was a nipple shield. I tried the bm, air dry, lansinoh, etc.
