Question
First off I asked this somewhere else, but only got one halachic opinion so I want to see if another one exists.There is a Halachic option that says if there are otherwise 9 adult (above bar mitzvah age) Jewish males, an underage (pre bar mitzvah) Jewish male can be counted to make a minyan (which normally requires 10 adult males). My question is, if a Jewish woman is pregnant with a male baby/fetus, and there are 9 adult Jewish men present, can her child be counted as a minyan with her present? Do any poskim disagree with the shulchan aruch’s requirement the child has to be 6+? And has a rabbi ever commented on this specific question? Sources appreciated
