All my experience with Mexican cuisine is coming in handy when it comes to swaddling my daughter in a blanket for easy room-to-room transport and general warmth. It's the same basic folding pattern as a fajita or a burrito. The particular picture below was the work of my wife. She looks like a package all wrapped up. All she needs is a stamp and a mailbox.
So far this pink blanket that a very nice woman named Sue at my father's work gave us is our tortilla of choice for wrapping our baby burrito.
Hey, whaddya know, there's an 11-step photo guide to swaddling on Wiki Commons. Unnecessary for anyone who's ever eaten a fajita.
