It can also be used to make milk bread, which is good for children and adults!
You can also do a good thing by bagging milk and giving it to those children who don't have breast milk to drink. If you are worried about the short storage time of breast milk after extrusion, you can buy some fresh-keeping bags, bag the breast milk separately and keep it fresh in the refrigerator.
However, because there is no preservative in breast milk, it can only be kept fresh for three days, and it will be thrown away after three days.
