We sure have discussed this a lot. I agree, yeast is a normal part of the body flora and there are antifungal properties in human milk. If the antifungal properties were enough to protect mom and baby we would not be dealing with thrush in the first place. The thrush, in my mind signifies that there is probably some compromise in the immune system to begin with and I would be quite uncomfortable saving yeasty milk in the freezer and reintroducing a large bolus of the yeast later. My recommendations are to err on the side of safety which, to me, is not to freeze milk collected during a yeast infection. This said, I certainly do not want mom's feeding formula, a dead substance and, in my mind, a bigger risk for yeast. Nearly all of the moms that I work with have regular separation from the baby and either formula or frozen milk is a part of baby's diet. If mom does not have time/supply enough to replace yeasty milk, I encourage her to scald the milk before use. This will kill many of the anti-infective properties, I realize, but yeast will not survive the scalding though either. These babies get much of the milk fresh and will get the anti-infective properties from the fresh milk, so the loss in the scalded milk should be less of the risk than the yeast with a dyad that may still be susceptible to yeast. I sure wish we had some evidence on which to base this practice!!!
