Sorry No can do, if you saved the game. If you didn't save the game, just reopen the game and play to rectify the situation. If you did... my apologies. :(
Well, you can play another family to adopt that child from the adoption agency. If no other children have been taken away, that kid will be the one that will show up. Then you move out an adult with the kid and then combine their family with the one that the child belongs in. Then you move the adult back out. I don't know what it does to the child's memories or if he will still view his former family as family members.
no memories. evidently the sims social agency is so trumatic it wipes the minds of the little dearies.
