I used the sunflower lecithin for the first and seriously feel like milk ducts are getting unclogged already...does it work that fast or is it the antibiotics finally kicking it? Mind that i had another duct clog today and I feel a little relief! Also another question! Think I’m going to start pumping and use my haaka...I still plan on EBF but just want to start building a supply so I could possibly stop early...how do I go about pumping whole EBF?
