When it rains, it pours... I'm on antibiotics for mastitis and now have pain in my other nipple. I don't see any white patches on me or in DD's mouth so I can't tell if this might be thrush or just painful sensitivity to DD's brand-spankin' new first tooth coming in and her desire to gum me to death. I'm taking probiotics and doing a vinegar/water rinse after each feeding, but wondering if I should get more aggressive with other measures. Besides the white patch stuff, is there any other way to tell if it's thrush?
