Invisible infant crib mod?

I worked real hard and it took me three days to finally make the infant crib invisible, but I was super disappointed to find out that it did not work like the newborn cribs. You see the newborns are objects in their cribs so they move with the crib when you move it, however our infants are their own little sims, so as soon as you move either a bed over the invisible crib, or try to move them with the invisible crib then they just reset and lie on the floor on their little tummy time mats. It is so frustrating, but I did try. So sorry I could not help :(

also to add, while testing there is not much you can use for the infants as well, you can only use their cribs or the toddler beds for height comparison, the normal beds are too high so you can't pretend to have them on the bed with the parents that way.
