I feel you, girl!
We co-slept with both of our girls, and when we got our first big girl bed, I would fall asleep night after night.
I like the idea of Daddy putting him to bed. We did that now and then, if I was tired, and knew I'd fall asleep.
My youngest still likes for someone to be in the room with her, so I'll grab my laptop and check emails or read for a little while, and she'll usually doze off in 10-15 minutes.
One of our other major strategies, was utilizing the power of "I'll be right back." Lay down with him for a few minutes, then tell him something like, "I need to go potty/I need to go tell daddy something/I need to go clean up the dinner dishes, I'll be right back." I'd go back in, if she was still awake, lay down for a couple of minutes, then remember something else I forgot to do, ". . . I'll be right back." It usually works pretty well, and assuming you go back in to lay down/check on him now and then, he'll remain comfortable in the fact that Mommy is still there, and will indeed come back.
But most of all, don't forget (and my hubby was pretty understanding on this one), they're only babies, -once-. If they didn't need that comfort and closeness, they wouldn't ask.
Best wishes and luck,
M.
