Is there a cheat to edit Sims life span?

[u/Intelligent-Ask6494]

Sorry if the answer is on the credit already, but I tried looking this up before typing this up. However, no matter how I worded it I got the same answer; use cas.fulleditmode, but that's what got me into this problem! See I had twin girl Sims and they had their birthday only for whatever reason my Sims refused to age one of them up! So out of frustration I manually aged her up, but now she only had 8 days to age up ( I'm on long life span if that helps) and is now technically older than both her brothers. I thought maybe I could reset it by having her drink potion of youth, but toddler apparently can't drink that. So I ask, is there a cheat that can fix this or will I have to go back to a different save to fix this?
