DS is 18 months old and all of a sudden my nipples are very sore. His latch is fine (so far as I can tell. HE opens wide and his lips are flanged out) and he isn't a biter. In fact it isn't even like when he was an infant and most of nipple and areola were sore. It's just the very tip and it's sore to the touch (and AWFUL while he's nursing). It's getting to the point that I don't want to let him nurse at all. I refuse to wean him before he's ready so I've GOT to find a solution for this!
