YOu've got some good responses...and each child is soooo different. Any new sleeping situ. for us called for trying it out at nap time first. I* would go thru a soothing routine, then make it really dark (we had to get the roll shades or he wouldn't sleep), put him in bed, and tell him he had to stay there with his head on the pillow. I put on music and sat in the room with him... not allowing him to get out. This was kinda time intensive at first but it gets better.
