Infants don't go into my crib correctly

Yes but I turned them off and had the same problem

Try resetting your user files as described in the factory reset described in this post: http://answers.ea.com/t5/The-Sims-4/FAQ-Troubleshooting-Steps-amp-Known-Issues/m-p/3621199

You won't loose anything. Just make sure to not delete any files  and make a backup.

After renaming, repair your game by clicking on the dots in EA app.

Try on a new game with nothing added back first (start new game). If it works, put back your save game and try again. If it still works, you can start putting stuff back.

• Options.ini (or just re-set all your settings manually)
• Tray Folder
• Screenshots/Videos/Custom music
• Rest of the save games (leave out slot_00000001.save which is the autosave and no longer needed - if you still have it)
• Custom content like clothing, hair, skins, make up ....
• ConfigOverride, if you have your own configuration files.
• Mods (one by one, making sure they all still work)

The rest does not need putting back, cause they are mostly cache files that recreate or log files that are not needed for the game.

Every time I try and put an infant into a crib, the infant will glitch through the sim's legs instead of going into the crib. When clicking on the infant it seems as if they are in their crib, but they are laying down on the floor.

I have this issue too! I don't know what mods if any could be causing this. 

I've also had this problem and sometimes when i pick my infant up, the legs literally stretch. Its so scary

I've been having the same problem. I turned my mods off and repaired my game and nothing has worked yet.

Having the same issue here, took out all script mods did nothing, turned off mods all together and it stopped the glitch.. I need my cc !! 

I have this glitch too. I’ve noticed if I wait for the infant to fall asleep, while they are still at the feet of the adult, then save and go to manage worlds, and load back into the household, the baby is in the crib. But I have to do it every time which stinks. But I didn’t have to disable my CC. 

i am having the same problem with the crib!! it includes the high chair too, the infant is sitting outside of it! it’s sooo annoying!
