Hi Pam I think I have seen what you describe. Mainly on black skin. Also, the staff at a couple of state hospitals have often queried what to do about the little black bits that shed off. Will it harm the baby they ask. Some nurses feel that it is a result of poor hygiene - I really don't think so. I have no idea what this is and look forward to being enlightened on Lactnet.
