I have tried it all..praising them when they go to bed, quitting the game after getting them to sleep at night...even the stuff to make them sleepy. But nothing seems to work. I finally started over and was doing fine until I quit for the night. I went back and found them exhausted, unable to stay in bed. I imagine that I will have to toss that family too. I loved the other games but am very disappointed in this one. I am sorry..its a great concept, but it makes the game unplayable for me. What was fun about the others is that I could leave it running in the background while I worked on other things and come back to see what happened. Now I have to constantly micromanage them to keep them rested. I hope the changes help.
