Suggestions:
1. Genetian Violet(not sure I spelled that correctly). You literally paint your nipples purple and it transfers to the baby when they nurse. Don't panic, the baby will get purple inside and out of the mouth and it will stay for about a week on both of you. However, everyone I know that has done GV has gotten rid of the thrush. You use a q-tip to paint yourself with the GV. I got mine at the pharmacy at our local Walmart, it is not prescription, but they keep it back with the prescription medications, so you have to ask for it. It was about $1 for the bottle.
2. Vinegar 1/4 cup to 1 cup water mix. Clean your breasts everytime after you nurse. Use a fresh mixture every 24 hours.
3. Go topless as much as possible. Yeast like the dark, warmth of a bra and shirt.
4. Take as much sugar as possible out of your diet. Yeast love, love them some sugar. Get rid of it for 3-4 weeks. As much as you can- no bread, etc.
5. Take some acidophilis or eat a bunch of yogart.
Also, I have read and been told that when the mom takes oral meds for a nursing yeast infection that you have to do so for 4+ weeks in order to get rid of it and that most doctors don't prescribe for long enough.........that the majority of docs prescribe long enough to make it decrease, but then after the mom has been done for 3-4 days taking the meds it flairs up again. My LC doesn't recommend mom taking oral meds b/c taking them for such a long stretch of time is hard on your liver.
I hope some of this helps you. You can overcome this!!!!!
