My favorite routine with Dash are his crazy baby stretches. We put him in a swaddler when he sleeps, and when he awakens, the first thing he does is a major, major stretch.
I don't know why we enjoy this so much, but we do. He's so into it, and does a good three or four massive stretches after every nap/sleep. With huge grins in between, of course.
EDIT: Now with video!
