Hi all. Just had to chime in here. When my son began cutting teeth the pad on his thumb split open and refused to heal. (He's been a thumb-sucker since before he was born!) A friend of mine who runs a pump rental station gave me some samples of the extra-pure-refined lanolin to try. I must say that the change was quite remarkable. Within 24 hours the split had closed and was beginning to lose it's angry red coloring. He never objected to the taste (yes, it was his sucking-thumb) and seemed much more comfortable with his thumb healed. I have never used it on nipples, but it works wonders on thumbs! ;-) Linda V.
