How to Source Breast Milk?

Before you decide to use breast milk for plants, do remember that first and foremost, it is EXTREMELY IMPORTANT that the baby’s nutritional needs are fully met. Use only the surplus that’s left after feeding the infant.

While sourcing the milk from a lactating mother, a breast pump can be used for the purpose.

If you are sourcing it from someplace else, you must declare the purpose (That it will be used for the plants) so that the donor is fully aware of how their milk will be used.

Use sterile containers to store breast milk to avoid contamination.
