I disagree with the people who are saying that maybe PJ had miscarried in the past. "Daughter" is symbolic as idoubtthat says. I think the daughter she is referring to is infact her younger self who was so innocent and perhaps upon losing her virginity she regrets it and yearns to return to her younger innocence ("That blue eyed girl became blue eyed whore")

The mother/daughter theroy also fits.
