Lyric discussion by DivingUp 

I interpret it as being about the loss of innocence... particularly when losing her virginity (whether by force or consensual). The daughter (blue-eyed girl) is symbolic of the innocent version of herself; the Mother is symbolic of herself after she looses her innocence... The "Mother" then longs for her innocence/innocent-self back.

It's really a brilliant song, and there can be many ways to interpret it, as with a lot of PJ's songs. She's a great songwriter.
