The core of the "pro-life" movement—maybe not the lay activists, but the true theocratic ideologues who push it—is not concerned about the fetus or baby itself.

They believe that God decides when life and death occur, and that, by permitting abortion, people are overruling the will of God. It is about defending God's prerogative over life, not about defending lives.

Hence, if a child dies an hour after birth, fair enough. God willed it. But aborting the child before birth, despite knowing it would die? That's interference.

Once you consider that the religious far-right's abortion activism is grounded in a specific reading of the Bible, and not in concern for the individual fetus or child, it makes much more sense.
