Is it permissible for a mother to breastfeed her seven-month-old child while she is two months pregnant?

There is no harm for a mother to breastfeed her child while pregnant, based on the hadith of Judamah bint Wahb al-Asadiyyah: "I had intended to prohibit ghilah, until I remembered that the Romans and Persians do that, and it does not harm their children." Ghilah is when a woman breastfeeds her child while she is pregnant. No scientific harms have been observed to affect the breastfeeding mother, the fetus, or the nursing child because of this. Therefore, it is not permissible to deprive a child of his mother's milk under the pretext of ghilah.
