Quoting Emilia's Mumum *JJM*:" It looks like an allergy, poor baby. I think you should switch to throw aways until you can get that ... [snip!] ... you can get that to go away! Because of how cloth works they are never 100% moisture free and it is probably irritating it."
She gets it when we use microfiber!! I have bought some other diapers that are 100% OBV and CV, but I planned on leaving her in fitteds that we have or dispoasables until they get here and it's gone. I would think if it was yeast it wouldn't go away in fitteds, which it does.
