Re: [FIXED] Parents keep taking infants out of crib for no reason
I've also been having this problem. My sim puts the infant in the crib and then autonomously takes it out again unless I manage to queue up another interaction first. Looks like this is same issue reported here, although I don't think it's mod related: https://answers.ea.com/t5/Game-and-Mod-CC-Issues/Struggling-to-put-infant-in-crib/td-p/12389370/highlight/true
In general, interacting with infants is glitchy. Sims will autonomously undo the previous action concerning an infant (e.g., taking it out of the high chair right after putting them in it) unless you queue up something else first. They will also often refuse to pick up the infant (interaction disappears from queue or they act like something is blocking the way when there's nothing there). And they're constantly dropping queued actions in order to "check infant."
