What can I do with the excess breastmilk that LO does not want anymore. Seems heart pain to just throw it away

Normally I will use them to give baby a milk bath or at times a foot spa for me! I had sent some to make some breastmilk keepsake and some mummy collect and sent them to make breastmilk soap. There is a group on breastmilk keepsake, they have a lot of different ideas to use "spoilt" breastmilk: https://www.facebook.com/groups/237406583102093/?fref=ts Breastmilk Keepsake: https://www.facebook.com/Precious-Lifetime-Memories-627589484011008/?fref=ts Breastmilk soap: https://www.facebook.com/tokensofeternity/?fref=photo
