We zip him into his sleep sack, sit in the rocker and read one story. Then we stand up, give him a hug and say "Time for sleeping. I'll see you in a little bit." Lay him down and flick out the lights on our way out the door. (He's mostly textbook with some old soul grumpy down the middle.)
Just have to add that we were in the airport a couple weeks ago, and our flight was delayed over nap time. E was getting really grizzly, so I looked at him and said "naptime?" I sat him in my lap, we read one story, then I hugged him and said "Time for sleeping. I'll see you in a little bit." put him in his stroller, covered him with his blanket and turned away. Within moments, he was asleep. My husband just sat there with his mouth open: "I can't believe that worked." I told him "of course it worked, E is a student of the Baby Whisperer!" (although secretly, I'm amazed it worked too...LOL!)
