Hi, just wondering how I would go about donating some extra milk? It's not a huge amount each day, but due to my son's milk transfer issues I have to pump after many feeds. I CANNOT give this to him in a bottle because it leads to frustration at the breast (after the ease of a bottle). I'm using small amounts in things for him but there's no way I will be able to use the whole drawer full of bm in the freezer. I will need to continue pumping and will keep having to freeze milk I can't use.
