I have a foster family I love to play. I move all my orphans or kids in less than ideal homes in with them. If you have parenthood and do the adopt as care dependent option, they will behave as the parents. I especially love the fact that when the kids grow up they will recognize their caregiver as a parent and family member. They wont show up in the family tree of course. My couple adopted the Villareal children. They all show up on holidays and visit regularly.
