K.W.
I would recommend going to see the lactation consultant at the hospital if you have tried all the other good ideas the other ladies had. I had the same problem with my now almost 4 year old from the time she was born they told me my technique was fine she wasn't sick just wouldn't latch for more than a few seconds so she gave me something called a nipple shield baby can latch easier she got her milk I used it for maybe a couple weeks then weaned her off of it straight back to the nipple no problems she self weaned when she was 2. Good luck!
