Sims3 lady is trippin out, out do I fix it?

I was playing sims 3 aand I had the mom teach the ghost baby how to talk. Out of no were she started sitting still and when I wanted her to stop she would'nt budge. It's acctually really creepy...she's just sitting there...stareing at the baby frozen...and now the baby is crying and the lady won't move (teach how to talk position) I tried to have her do something else but it won't work, I also tried to do super satisfy but that won't work either, I saved and quit the game but that don't work either, I tried to have someone else take care of the baby but that don't work either. How do I fix this???(the baby is crying and I don't want cps to take the ghost baby)
