You may have the same problem as me, so to be preventative, read on:
My nips have been unbearably sore with a few blisters for almost a week now, so I've just been pumping.I contacted my LaLeche lady, and she figured out my problem:
My one month old has nipple confusion! I just thought that nipple confusion meant the baby wouldn't take one or the other, but he is latching poorly now because he was getting used to bottles...(I was using them alot because we did so much visiting for the holidays.) I was using the worst type of bottle too, the VentAirs, because the base is too wide, nipple is not long enough and the bottle is angled! Who knew? The nipple package says best for breastfeeding mothers because it's more like the breast!!!
According to this doctor, it is not the case, and now I have to 'train him' to get him to latch on better. Read here:
The reason I am getting sore/blisters is because he's using his toungue like he would with a bottle, I tried feeding him like they suggested & with a better bottle, and he took to it like a champ, hopefully in a few more days we'll get better...I sure hope so because I plan on sticking with both ways of feeding him when I go back to work.
Hope this helps if u need it, she also gave me instructions on how to train the baby's tongue. Let me know if u are interested.
