just recently I noticed my baby had thrush of the mouth. After reading the La leche Leauge website it said that the medication my doctor prescribed for the baby (Nystatin) is not effective. I was also wondering what I should be applying to my own nipples in order to keep from cross contaminating the baby. She prescribed me nystatin CREAM to apply to my breast twice a day. Which I do not understand considering this would be dangerous for my baby to ingest. If anyone has had this problem can you please help me.
