Donating breast milk

Q: I have a question about whether it would be allowed for a Muslim to donate breast milk for use by babies. Secondly would it be allowed for a Muslim mom to allow her baby to use donated breast milk on a newborn infant.

Background information: bottle feeding is both expensive +\- minus R400 per month and needs to be sterilized. For the poor person who is unable to breast feed, mom who's dead or too ill this could lead to serious illness in the child. For instance over diluting to save money would lead to malnourishment. Or people without access to electricity may not heat the bottles leading to child getting severe infections.
