I moved a sim into another sim's household and I want to turn them from roommates to mother and child but I either get a "cannot edit pre-existing sim or the only options I get are "sister/brother, roommate or wife/husband." I changed their ages and the cheats are on both testingcheats true and cas.fulleditmode but it still doesn't give me the parent/child option.

I know I'm a little late, but I had this problem when I made a brother and sister and forgot to edit their relationship before placing them in game. I fixed it by going into manage world and editing their household. I added another sim and set it's relationship to their mother and it automatically changed their relationship and then I deleted the sim. So I assume if you wish to do it with a mother/child for example, make another child, set them as siblings, then delete the unwanted one.

@beeke404 These relations must be set before the game starts and later unless you have MCCC mod, nothing can be done.But this can be solved differently.You can save all these sims to the library. Enter with these sims in the CAS outside the game and set these relationships between them.Switch to a random family in order to save the game and remove the family you played from the game. Then enter this family from the library again into this game on an empty plot. They lose all friends and money but their careers and skills will stay. You can add money to them with the motherlode code and put them in their old home.I don't work for EA

relationship.add_bit <yoursimID> <targetsimID> <relationshipBit>So, if your grandchild ID is 123 and grandparent is 789, it would look like this:relationship.add_bit 123 789 family_grandchildThat being said, I have no idea if this cheat works anymore. A lot of cheats (like the skill cheats) were taken out of the game a few months ago. There is a mod out there that will re-enable them. Try searching for TwistedMexi sims4cheats or viewing https://www.carls-sims-4-guide.com section on cheats for more info/help.

Here is information I took from someone else. I would credit the original author, but I don't remember who it was. This has worked for me...****************************1. Open the cheat console ctrl + shift + c and type: "testingcheats on"2. Now type: "sims.get_sim_id_by_name yoursimfirstname yoursimlastname" (The desired sim must be selected)-It will pop up a large number. This is very important. This number is your Sim ID3. Type again the same thing in step 2 but now with your desired target sim name.-I mean, if you want to change your (example) son and mom relationship, you need to type the text from step 2 from both of themYou should now have 2 large numbers in the console. (SimID)---MAKE SURE TESTINGCHEATS IS ENABLED, AGAIN! OTHERWISE THE NEXT STEPS WON'T WORK----In step 4 you will write your desired relationshipBit. (Obviously I mean, don't write the word "relationshipbit") you need to overwrite the word with These relationshipBits:*family_husband_wife*family_son_daughter*family_parent*family_grandparent*family_grandchild4. In the console, type: "relationship.add_bit yoursimID targetsimID relationshipbit"-YoursimID is the large number you got from your selected sims. You need to write the whole numbers.-relationshipbit DOESN'T NEED TO BE WRITTEN, it needs to be one of the 5 commands I wrote in step 4.If it doesn't work, it's because for some reason, Testingcheats disabled automatically (It happenned to me several times) Write it again and make sure its enabled again, and repeat the step 4.******************Good luck!

@beeke404 Here’s another way to try1.Testingcheats true 2. Cas.fulleditmode 3. Shift click sim to modify in cas 4. Save the household to your library 5. Click “X” in cas should say reset household. If it does click reset household And go into your library and click the household you wanted to change the relationships for.If you WEREN’T able to reset the household make sure to still save the household to your library then go into the gallery switch out the household for another one then click replace. After that go back into the library click the household you wanted to change the relationship for and click replace and then try changing the relationship status.

Holy cow, I just cracked the code 😛
Here's what I did:
Separated and created new households for all "pre-existing sims"
example: sister and brother were in a different household as their mother, so I created a new household for the sister, new one for the brother, and a new one for their "mother"
Saved them all individually to my library
Created a new household in CAS
Added all family members into "new" household individually from my library
Modified all relationships
WAS ABLE TO GIVE MY SIMS THEIR MOTHER BACK :D
~~(1 year later...)~~
sidenote: I have been scouring the web to make this work for WEEKS and tried EVERYTHING from -what seemed like- every forum. mods haven't been too kind to previous save files so the family I was playing with (my generation run). So, I removed them and started fresh. 6 months later, wanted to try mods again but didn't want to ruin my save files. Saved a family member, modded her, and played her quite a bit. However, I was really missing having the fam around. So I saved them and brought them to my modded save file and couldn't fix their relationships (why didn't they follow???) and came across this puzzling issue. Took matters into my own hands. Hope this helped!! (hopefully i'm not the first to figure it out either) (sry new here)

Wow, that's an awful lot of work to achieve the same thing.
You don't have to go through all that. You'll end up losing ALL relationships with EVERYONE like that.
Just delete the existing relationship. The options to set relationships will magically re-appear.

I think if you load your game, then click on manage households (don't just press play), then you can manage your household relationships one by one by clicking on each of the sims and editing them.

@meeshmeesh3 Unfortunately that doesn't always work. Sometimes CAS will refuse to allow you to change the relationship between two sims, and you get that error message. The ONLY way to do it is to use either MCCC or a cheat to completely delete the existing relationship. (make them strangers to each other) then you'll be able to edit the relationship in CAS.

@RouenSims This definitely doesn't work. Your instructions are semi confusing but I've used sim ID cheats before and they worked (for pregnancy, etc), but this definitely doesn't.

@Psychotps I deleted this sims family and she still can't become my sims daughter.

I made a household of 4 sims and played it for a while before realizing the father was the step father of his child. This is because I forgot to make them father and daughter in CAS, but I used the cheats testingcheats true and cas.fulleditmode repeatedly and nothing happened, they did not become parent and child. I don't have MCCC. Can someone please help?!
