I can't figure out how to do this. I currently have an Ergo and a Moby wrap. I also have a pocket sling, but don't like it much. I can't figure out how to wear the Ergo and Moby at the same time. My twins are only 8 weeks old right now so I can't do a back carry anyway, but I'm still stumped. I'm thinking about getting a Mei Tai because that seems to work better with the Ergo, but I'm not sure.
Basically, if you wore your twins, how did you do it? I'd like step-by-step instructions, if you don't mind.
