Re: nipple damage
Yes to all that LLLMeg says on latch.
I just had my second and got cracked nipples and my IBCLC gave me a crazy treatment that worked incredibly well. Take 1 drop of Dreft laundry detergent and put it in a cup of warm water and soak the nipple for 4-5 minutes. You can use like a shot glass and hold it on to your nipple. Then air dry VERY well. Then apply a very small amount of bacitracin ointment (bacitracin only, no other antibiotics like neosporin). You'll want to wait an hour before nursing again. Do 1-2 times a day. I only had to do this 3 times before my (minor) cracks healed enough to tolerate.
