You mentioned in another post that your fiance and his sons were moving in. Stress can cause problems. Nightmares can cause nocturnal enuresis. 2 hours before bed don't have her drink anything and as the other poster said, have her go to the bathroom before bed. Get her up to go to the bathroom in the middle of the night. If you go to bed late and she goes to bed early this can be right before you go to bed. You can also look into bell and pad systems that will wake her up if she starts to urinate at night. Have her help to clean it up, but don't scold or punish her. Be patient with her. I know her behaviors are very trying, but try to remember all she has been through and that she is dealing what that at the same time she is dealing with everything else.
