Don't have breastfeeding references per se but, I freeze my baking yeast to
preserve it for long term storage.  Even though we are talking about
different types of yeast, I cannot see any reason that nipple yeast would
not also freeze quite nicely.  I recommend to moms with yeast that they not
freeze milk, refrigeration is OK because most milk pumped during a yeast
infection would generally be used while still under treatment.  Not
documented, just my way of looking at things.
