R..
I would try a nipple shield first... maybe that will give her the little bit extra she needs to get a good latch. While my DD didn't have any latch issues, she was soooo slow that I eventually started exclusively pumping. The biggest thing that helped me there was to rub a fair amount of milk onto my nipple to 'lube' it up. That stopped the chafing, which was causing most of the pain. I also rubbed milk into my nipples AFTER pumping and let them air-dry for 5-10 minutes afterward so they could have a chance to heal from the pumping. When my DD was 3 months old, I was finally able to start feeding her from the breast full time again. :) Good luck!
