I think I understand the point you are making here, Ditto.
But I would point out that a child begins to live as soon as a new human life begins.
And that happens, if I remember my high school biology well, at the moment of conception.
A child that is not-yet-born is still a child that lives.
And the woman who carries that child is still a mother.
I think, anyway.
But can one who "chooses" to cause the child's death, be considered a Mother in any sense of the word?
