Infants not going in crib

I was of the impression my particular save was glitched, but now everything beyond that Save As is also having the Infant problem. I will do a game folder reset and make yet another copy of the back up before I sally forth. I'm so very frustrated at the moment I could chew nails. I tried to find a thread over on the help thread, but nothing of this sort has been reported. The Infant slides through the rails of their crib to become trapped between the caregiver's feet. There is no interactions going on unless you count the fact that the Infant gets dragged across the ground or floor or whatever. This wasn't happening in my game initially. It only began, to my knowledge, when I tried a game save recovery to try to have a proper birthday party for the first born. GAGH.
