I know of nowhere in Jewish law that a fetus is given less value than any other human life. It is only when a choice must be made between two lives, where a woman may kill or have her unborn child killed, as an act of self-defense.

[DonQ]

The Jewish attitude about a fetus is vague. There are some provisions that treat a fetus as a living person, but in the case of a stillbirth or a miscarriage the fetus is regarded as never having lived and therefore a number of religious laws and rituals applicable to a baby who died after drawing a breath are not applicable.
