Thanks to all for the various ideas posted in response to my original post about yeast living in a diaphragm. Actually - I am *real* sure that this is what has happened, despite the lack of written information or midwife's knowledge about it, as I have considered all the other possibilities that have been raised and have been able to rule them out. Mostly I wanted to let everyone know that when you're helping a mom who's got a yeast problem, it is one more thing to consider - and I know that without documentation it may be a tough sell, but it's worth thinking about. I've gotten private e-mail from two LactNetters who think they've had the same problem, so I know I'm not the only one who's suffered out there although I am the only one who's posted it to a list of almost 800 people!!!!!!!!!!! Pat Drazin's comment about yeast living on paci's seems particularly apropos and is certainly evidence enough for me! If I find out anything more about what sort of treatment IS okay (heat, chemical?) for a diaphragm then I'll let y'all know. Mary Renard feeling rather dough-y since Christmas, rather than yeast-y :-)
