Sadly, special care nurseries around Vic at least, in both regional and city hospitals, are full of newborns going through withdrawals because their mothers (and fathers if involved) do exactly what this mother has been doing. It's not a nice experience when a newborn screams continually because it has f***ed up parent/s. Bu tit is far more common than most people would be aware of.
I'm living in fantasy land I know, but still holding out hope that her mother didn't betray her.
