P.G.
I made the same mistake one time but with a little more intense stuff like JASON and CHUCKY- that was bad. I am also a single mom and had the same problem, it started effecting his school work where they would draw a pix of a dog on a sunny day, the dog would have a knife or a devil on his back- crazy!! I understand what you are going thru, believe me just keep the consistency going, put him back in bed every time he does this, adventually he will get it. Once I even let him sleep late during a "boring" movie, when he would fall asleep I would put him in his bed and he would wake up in his own bed wondering how he got there.. YOu will be fine, soon you will miss him in your bed= so enjoy while you can :)
