We saw a 28 year-old G2P2 mother of a one-month-old at the clinic recently who reported getting a "metallic taste" in her mouth when her baby latched on. She had nipple yeast and had had a crack at the base of the right nipple since day one pp. The metallic taste was associated with the pain of latching the baby on the right breast. A week after her first visit, there was no longer any latch-on pain. However, the metallic taste persisted for another week or so until the crack was completely healed. Interestingly, when she returned for follow-up she reported that her sister had had a similar experience with a metallic taste during breastfeeding when _her_ nipples were damaged while nursing some time previously. We have never encountered this before and I have not seen any reports of this in the literature. Have any of you heard reports of or had experience with a metallic taste associated with nipple yeast, cracks, other pain, MER, or anything else? TIA, Karen Grue R.N., B.Sc.N., I.B.C.L.C.
