"Baby" and "Fetus"

Interesting that this article in the NYT about pregnancy consistently refers to the "baby" and not the "fetus."  How would it come across if the terms were switched?  Could it be that we have conferred on parents the right to define the unborn as a baby if a baby is wanted, and the right to relegate the unborn to the status of a fetus if a baby is not desired?  Makes me think of the chilling but important commentary of Matt Walsh:  "Apparently Unborn Babies Are Only Human When They Belong To Beyonce."
