Sims parents gone crazy can't get them to sleep

[lisalisa]

Both of my sims sleep bars are in the red and they gave already passed out on the floor. But, when I click for them to go to sleep it will show for a second but they won't sleep.
I can get them to take small naps. Anyway, they keep taking the babies out of the crib, downstairs and so on. They won't sleep and are acting wacky....

Couple of things:
If you have mods, that is most likely the problem.
If not then:
Try resetting them. resetsim Firstname Lastname
Try deleting the bed and buying it again.
Make that there is nothing in their way and it is possible for them to get to the bed.

And I doubt this but if their relationship isn't high enough they wont sleep together but that doesn't seem to be the problem here.
Hope this helps!
