Not exactly our best photo, but Hubbo was out of town on a business trip. Here we are using a Babyhawk mei tai-style carrier that I rented from our "local" babywearing group.
I really like this carrier now that E is sometimes a bit squirmy for the Moby, and I've read that it isn't a good idea to wear a baby on your back with a stretchy wrap. In fact, I ordered my own, and it's supposed to arrive today! Since it doesn't have any buckles, the Babyhawk is more adjustable than the Boba I tried a few months ago. It's a little more complicated to put on, but I can actually make it snug enough to do a back carry.
