Infants kinda buggy

Heyy, I don't know since when this bug exist, but it can't be that long. I can't do nearly anything with the infants. I can't put them to sleep, I can't change diapers. Because the command doesn't even exist. 

And I moved all my mods out of the game and tested it. I even fixed the game and tested it, also without mods, even then it doesn't work. 

Anyone knows the issue? With or without mods, it's the same result, can't do anything with the infants.

Pls help
