I dont think it would be a good idea for her to sleep in your bed cos needing a litter tray urgently comes with the problem.
As Jack snows I have been there and to be honest there is no solution but keeping them , their bed , water, food all in a smaller room may help but dont think it will stop the wailing.
Kocka would wwail most of her none sleeping time unless i was with her, on the floor and next to her.
