>>It is now week 7 1/2. It appears the thrush is gone (YAY!) The thrush disappeared after each round of Gentian violet, but returned in about 5 days, until I got put on Diflucan (I had to change doctors to get the Diflucan, but that is another story).<< From what I have heard, gentian violet needs to be repeated after a couple of days for a total of 2-3 rounds. Sounds like baby was simply undertreated initially (too conservative) and yeast not entirely killed, not unlike forgetting to take a full course of antibiotics.
