M.H.
The Crawling is fine. I would just put him in and let him alone, he will figrue out how to go to sleep.
We have a homedics music box that projects stuff on the ceiling, we can set it to a timer or not.
If you do not need to be in the room, I would not be..he might learn to depend on you bieng in there to go to sleep.. see how he does with you laying him down and walking out.
