All of my bags of milk are 4-6oz. Most of them have 6oz. Some even have 7oz. I am an over producer so I have a lot of extra milk that I don't want wasted. I would love to help other babies/mama's in need. NO wet nursing. Only form of payment accepted is through PayPal. Buyer is also responsible for shipping charge and packaging materials. I am a healthy mama with a good, clean diet. I take daily vitamins and supplements. I also limit how much dairy I eat because my baby has a sensitivity to it. So my milk may be ideal for you if your baby has the same issue but I am not completely dairy free in my diet. All milk has been frozen same day pumped.
