Trying to add a child to an existing family? *solved*

Ok so Don Lothario and Nina Caliente had a kid in my last save and I just love her. So I saved her and am trying to add her to their family in my new save. I am using the cas.fulleditmode cheat. However I can only make one of them her parent. When I try to add the other it just defaults the other back to roommate? Is there some way to do this? What am I missing here?

EDIT: Ok so I figured it out so never mind. If anyone is wondering or runs into the same problem don't add the child to the family from the world edit screen. Actually play the family then enter the testingcheats true and cas.fulleditmode cheats. Then shift slick on one of the family members and use the option there to take them into CAS. Then in the CAS screen you can add the child to the family and it will let you edit the relationships.
