I am a surrogate with a surplus of frozen breastmilk. I have sold or donated over 25000oz to date, I am happy to share blood work to prove i am clean and healthy. Surrogate baby was born healthy, parents did not want the milk. Bags are in 4oz but mostly 6oz bags, frozen very flat. I have been giving the milk to my own toddler, who is now 3.25 and is naturally weaning off of the breastmilk, leaving me with approximately 2000oz leftover.
