Woman breastfeeding her sister's children

Q: Is it permissible for a woman to breastfeed her sister's children with the intention of making them mahram to her children?

A: If you breastfeed your sister's children in the period of breastfeeding, then they will become foster brothers and sisters for your children. Hence, they will not need to observe purdah among themselves, and they will not be able to marry each other.

And Allah Ta'ala (الله تعالى) knows best.
