Judy Eastburn, I don't know if this is the same as what I called "blisters," but if we are talking about the same thing, I had them with my twins, starting about two months postpartum. Mine had a clear liquid escape from them when they broke open (usually when the twins nursed, more rarely with friction from clothing). They were always on the tips of the nipples, usually started in a groove. It's the "10 days from formation to healing" that sounded familiar, because that's how long it took mine. Treatment: I just grit my teeth. My LC recommended (phone consult) eliminating chocolate and peanut butter from my diet, which I did, and I think may have helped. As the babies got older, I saw them less frequently, and had the last one when they were about 18 months old (that's a long way off for your mom!). Reassure your mom that, assuming we're talking about the same thing, they probably won't go on forever. Pain is a negative M&M, however. Less frequent nursing helps, as does limiting the length of the feed. These measures will be easier to implement as the twins get older, so if she can just hang on.... Susan Betz
