I had Jared take his daughter away from her mother (his ex Claire Ursine) via edit town, no cheats, high free will, and he bonded with his daughter quite well. Claire did not beg for her daughter back once, nor did she attempt to visit her. When I sent the baby back with her mother, her social meter took a nose dive and Claire was just sitting there watching TV, while the baby was screaming and crying. She was warned by the social worker, so I moved her back with Jared. So in my expierence, cheats or no cheats, Sims don't care about what happens to their children and/or exes until it's too late. I also should add that none of Claire's wishes included "quit job" but did include "earn promotion" "join theft branch" and even "make level 7 of Criminal Career" and also to "slap Jared" while Justine and Marty always want to "Snuggle" "Pick Up" and "Play with" their baby boy.
Basically, it all depends on the Sims parenting wise. The good parents' wishes always include "snuggle" "pick up" and "play with" and "quit job" (Keaton Family, Jared Frio) while the bad parents (Claire Ursine, Alto Family) don't have the "snuggle" "pick up" "play with" or "quit job" wishes, but have "promotion" and "advance" wishes Vita and Claire both want to steal candy (sometimes Claire has the evil trait, cheats or not) from their babies. Stealing Candy makes babies' social meter go up too, and the relationship meter actually goes up.
