In Sims 2 I think it was, I had a sim and it was so hard to get her to take care of the baby, well the social worker took the baby, I was so mad about that.
Well I had her get pregnant again, Only this time when the baby was born, I put her and the baby in a room and took out the door. I put a bed and a table and chair, Ref, toilet, shower and ect. I then made her take care of the baby until he grew to a toddler.
The Father went crazy, trying to get to her. but guess what they did not take the baby this time.
