@Viktrodriguez Would you be able to ask this question on the Dutch page of Answers HQ? I would like to look into this situation and help Dutch readers at the same time.
By the way, MCCC could provide a solution as
@jaxandel suggested, but you have to use the console options to make it work fully.
The situation in this case is that you in fact created a completely new Sim with the same name as the former that, you state, was culled. Bringing back 'the mother' and as you call it 'the child' does not make them family members in the game, nor in your household. The only way to recreate such a situation is by going to CAS an recreate a family bond by using the option 'play with genes' an load this family back into your game.
However if that doesn't suit your needs or the way you play the game, the only way is to use the MCCC option in which you can alter any type of relationship. When you google mccc, you will be directed to the page almost instantly.
Have fun playing 😉
