Need help with my game

I would like to know if there is a way to avoid having the social worker take your kids. One of the kids missed the bus. This one has a D for a grade, then later in the game it becomes an F. There is a Nanny there during the day for the baby, who seems to be doing OK. All of the adults living in the house went to work. No matter what I do, the social worker shows up and takes the kids, after the Nanny leaves and the adults come home. I think the Nanny turns them in. I have had the kid invite a person into the house who was passing by, but not a family friend. I have tried toget her to do homework to get the grades up. What can you do? Is there a way to get your kids back after they are gone? I don't save the game so I can do over, but nothing has worked.

a way 2 get social workers from taking your kids is to type in move_objects on in the cheat window and when the workers come, click on them and delete them.
