[MOD RELATED] Newborns age to toddlers/Disappearing infants

I’m currently having the same issue… even when I take all my mods out and repair the game it still does it. My newborn doesn’t even turn into an infant , it turns into a whole toddler. I was very excited to play this pack but now I want my money back. 

What mod was it

it's like i never even updated it, but when i go into my sims it shows up with the growing together pack and with the infant video, but in cas and a new save infants don't exist. i don't understand i've tried repairing my game, i've signed in and out of my EA account, and i've tried uninstalling and reinstalling sims.

I have no screenshots, however my sim had a baby immediately after updating my game and it appeared in my household. I went into CAS to manually changed the baby's age to an infant. I went back into live mode, and the infant was there. I opened build mode to make her a room, and when I went back to live mode the infant was no longer in my family. I tried to manually create a new infant in CAS, and it will not appear in my household. I have closed and reopened the game multiple times, attempting the same thing. 

Is that a real solution? Really?? Many of us love playing using all the CC and mods. Isn't there an easy way to find out what is the mod/CC glitching?

For everyone saying they removed all their mods, deleted the localthumbcache file and still don't have any infants, could you please post your FULL version number.

You can find it on the right bottom corner of your main menu,

This bug was for me caused by mod by weerbesu "More Columns in CAS v1.27". It was the updated! version.

Edit: Sorry I got confused. It was actually one of the mods from Sims4Me (Bienchen). Not sure which one specifically.

I wish that were the answer for me! I don't even have that mod. About to spend the day using the 50/50 method... I have a lot of mods... I'll check back in when I have some answers.
