Is there any halachic concern with breastfeeding on Shabbat? I believe the chazon ishChazon Ish brought down one can’t milk a cow on shabbos (which I disagree with personally), but under his logic would a similar issue present itself with breastfeeding from a human mother? I know technically, babies are not obligated to keep Shabbat, but would this be an issue of lifne iver on the mother’s part (at least according to the logic of the chazon ishChazon Ish)?
