I changed my mind and would like to adopt other kids. I would like to do this without killing my children (I'm not that evil) or using the 'disable' console command on them permanently (removing them from the game), kind of like the solutions for obtaining a divorce without killing your spouse, so you could remarry.
I'm playing on the PC and would welcome solutions that are mods, console commands or save game editing and that won't have children killed or disabled (removed from the game). Preferably, they would still be alive and be back in their previous homes (or the streets) after the un-adoption.
Research info: I've searched and these are some of the forum posts I found where the same question is asked - but they contain no solutions. Some of the replies mention killing the children or using the 'disable' console command, but this won't actually 'unadopt' the children.
