I don’t recall saying anything about ‘healthy’ babies.
Sometimes miscarriage happens because the mother is in some way unhealthy.
Miscarriage is Nature’s way (God’s, if you prefer) of ending a nonviable pregnancy.
To any rational person "healthy fetus" indicates the baby is viable. But for those who wish to justify remote cooperation with murder, I guess they'll just make stuff up.
Is elective abortion God's way also?
