Does S 81 Address a Custom of Burying Baby Girls Alive?

S 81:8-9 “And when the maw’udah has been asked/ Which sin it was killed for.” Maw’udah is, so we are told, a nominative feminine passive participle. But there’s no obvious explicit mention of a baby girl, nor apparently of one that has been buried. Could this verse be in reference to the human soul, nafs, of feminine grammatical gender? If so, the maw’udah, of uncertain etymology, could arguably be about a male or a female of any age being asked what sin he/she had been killed for, in whatever manner.
