To change Sims’ names, simply choose “Change Name…” option on the city hall. Also, save your game before, just in case. Note that you should only be able to do this if the Sim has been aged to a child though, babies not being available in CAS. Is there a way to edit? Shift + Click on your Sim and click Edit in CAS. Can I change the gender of my baby Sims 4? Consider hiring a Nanny via phone if you get overwhelmed taking care of them all. Re: Sims 4 baby taken away You can load an old savegame to get the baby back.
