I have a chair next to my DDs bed, and DH or i sit next to her until she falls asleep. Sometimes it only takes a few minutes, other times it is much longer (almost 2 hours last night). I hope to eventually change to staying til she is settled and then leave and go back and check on her, but i don't think we are there yet.

If you have just moved your little one, he might need reassurance for a few nights and then be ok with going to sleep again.
