Hello! Can you tell me who has had thrush in their mouth? My daughter got it after antibiotics and she still can't cure it. We went to see a doctor. She said to treat candidiasis, so I am doing that. It seems like it is going away. But then after 3-4 days it appears again. Maybe there is something else that could help. The pediatrician says all the same thing.
