Thanks for all the responses about the persistent thrush...mom has been on fluconazole now for 3 weeks and is totally asymptomatic now, so that confirms that her symptoms were largely thrush...the baby is still having what looks like thrush on the tongue...I saw it under the microscope along with my lab tech, but the culture we did was negative. I am going to send her to a dermatologist. The tongue has not changed with nearly two weeks now of oral fluconazole. Mom says that she has done everything she can to eliminate yeast from vectors in her household...I am not convinced that her dietary changes have been very thorough, but I know that it is very hard to eliminate all sugars too, so I try not to lean too heavy on her. I'll let you know what the dermatologist thinks-Anne Eglash
