Is it necessary for the five breastfeedings that establish a milk-kinship prohibition to occur in a single sitting, and what if the breastfeeding is via a bottle?

The questioner:
Honorable Shaykh, may Allah grant you success, he says: The breastfeeding that establishes a prohibition is five feedings. Is it necessary for them to occur in a single sitting?

The Shaykh:
No, five sucks, meaning, it is not a full meal, no, five sucks where each suck brings milk to him. So if this happens five times in one sitting or in multiple sittings, the breastfeeding that establishes a prohibition has occurred.

The questioner:
Then he says, may Allah preserve you: What if the breastfeeding is via a bottle and not direct sucking from the breast?

The Shaykh:
It is the same. As long as it is the milk of a woman and he has sucked it five times or more, it establishes a prohibition whether directly from her breast or via a bottle.
