I have a ridiculous amount of extra milk frozen, I’m an overproducer. It is frozen in 6 ounce bags. No illegal substances or alcohol or tobacco. I do take a prenatal and sunflower lecithin (this is totally safe and used for prevention of clogged ducts) nightly. I have proof of clean bloodwork as well. All pump pieces are sterilized after use and milk is stored in a deep freezer that is specifically for milk, so it’s only opened to add more milk. I do have one cup of coffee in the morning, otherwise no more caffeine. No dietary restrictions.
