At first glance (and second, and third . . .), I was completely intimidated by my Moby Wrap ($38). The versatile sling is one superlong piece of cotton, and to see it on its own, it's hard to fathom how the fabric could safely hold a baby. But once I watched the online tutorial and tried tying it on in front of the mirror a few times, it became a staple of life with a newborn, freeing up my hands while keeping the baby cozy and secure.
