should I do? I want him to learn to sleep on his own because for the last few nights he has been sleeping with me so I decided tonight was the night to start! I know he should stop whining after a while, I put toys in there, some newspaper and his crate with the door open! should I leave him all night? will this confuse him when it comes to potty training? will he ever stop whining? and should I have left the light on, its off now should it be?

and how many night will it take before he doesn't whine at all when I put him in there? will he ever get used to it?
