<<Disclaimer: Verify this information before applying it to your situation.>> Breastfeeding is best for any baby, any species, always. This is a fact that is not argued anymore between any health professional. CD is a genetically predisposed disease not a disease of exposure, and gluten proteins are too large to be passed through breast milk. This was from the last breastfeeding thread I remember on the list. Someone may be able to access this through the archives, I don't know how and don't quite have the time. Before you treat thrush with gentian violet you need to be aware that it can cause permanant purple discoloration on the nipple. Thrush in the mom is evident because the let down will sting very badly in the nipples. Thrush in the infant is evidenced by the familiar white splotches in the mouth. Both mom and infant should be treated if either are symptomatic. There is a product available by prescription only called nystatin that kills the yeast causing thrush. It can be bought in a suspension or cream. The mom can use the suspension on her nipples but it gets a little sticky. It should clear up in 3days to a week. Not meant as medical advice but information. The thrush info comes to me from the Le Leche League, and WIC, and is standard of care in the US. I am a pharmacist. Hope you get relief! Cindy in Texas
