My son and I fought thrush for 2 months. I did give him Gentian Violet. I was originally told to give it three days in a row, but then after the villonth of getting back, they said do it 5 days in a row max, on me and him. It is messy, I used a Q-tip and had old clothes on him so when he drooled, it wouldn't matter. I did notice however that the stains did come out of some clothes or atleast dulled down a lot. The only thing with gentian violet is you need to watch he doesn't get ulcers. Good Luck!
