Go to Home Depot, or any similar store, and buy bolts for every door in the house. Locks that would be installed on every door (inside), and would be locked with a key only. Put one of those 'bolts' on each door and lock them at night. Keep the keys in a secure place. If she can't open the doors....well then, she can't get out. Unless she's crazy enough to break the windows, I think that should work in keeping her inside the house.
Good idea, but very dangerous in an emergency. My cousin is a firefighter and says these things are killers. In a fire people tend to panic. Or what of you and your husband were already dead/passed out from the smoke, but the kids were alive and couldn't escape? Believe it or not, people will freak and forget that there are windows to break and escape through.
