Sims 4- Sims not eligible to age up.

Hello, I am having the same problem but it only started today. I was convinced it has something to do with the size of the household because I have four women and their children in the same house. None of these four babies have the age up option, and all four women are ineligible to use the birthday cake. I took one away with her child and tried to initiate aging in her own household but that doesn't work either. I don't know if it's the same for you, but my whole town is frozen in their ages. I am curious if you use any mods. I use a mod to allow teen pregnancy and various other script mods, such as simocide. Maybe there is a specific mod reaction built into the game to stop it from working. The only thing I can think of to do is talk to someone from EA, and that is why I am going to start a live chat with an EA employee in a moment. If they tell me how to fix this, I shall let you know.

***UPDATE**

As per usual, their chat servers are down, but I think I have found a fix! Temporarily turn aging on and age up whoever, then turn it off again! This may only be a temporary fix to a permanent problem, but I will still be persuing contact with an EA employee. I hope this works for you!

how did you turn ages on?

For some reason no mater what I do I cannot get a menu to age up babies? I know I am not alone in this as I have read about this issue till my brain feels like it is blowing up!! Is there a fix for this or do we have to have babies forever? This has just begun as a month ago I was able to age up the babies. Please if there is a solution to this problem let me know.TY

This has not worked for me ;(

Are you using any mods in your game ?

I have this problem with a child.  So I played another household that had a child and was able to age that child up to a teen with no problem.  I went back to the household where I encountered the problem and I still get the message the child is ineligible to age up.  So, it's just that child in that household.  Will try turning aging on as you did and see if that works.
