I'm pretty sure it's a female. They do have to pay child support, too. If sh/it was living in a "polywhatever" relationship with 2 men...doesn't the "poly" part imply that they have to be more than one gender (or undecided, at least). I feel sorry for the kid. Can't imagine any child having to grow up in that chaos. Terribly confusing & abusive.
