Is the prohibition established in breastfeeding if it is done through a plastic bottle?

The questioner : The Shaykh (may Allah preserve him), a woman breastfed a girl five times, but she was putting the milk in a bottle. Is she forbidden to her by this breastfeeding, even though the amount of each feed is small and hardly means anything?

The Shaykh : Now, this woman who puts her milk in a bottle, does this milk that was put in the bottle turn into orange juice? No, answer: it does not turn into orange juice. The milk is milk; the milk is milk. So we say that the criterion is the meanings of things, not their words. His saying, Mighty and Majestic: There is no doubt that direct breastfeeding is more effective, because the milk comes from the woman's breast to the child's mouth, and all the elements in it do not change, because there is no possibility of them changing. But if it is put in a container and drunk, it must change, but the original substance remains.
