Yeah, I never figured it out. And I really, really tried. Even if I could get on on my back and one on my front or them both into the same wrap on front, I couldn't move at all and was instantly exhausted. I feel bad that mine don't like being worn and I wonder if it's because I didn't wear them enough. They usually won't tolerate being worn at all. The only exception is when we've been out way too long and really need a nap. They'll sleep in a carrier because they can't really nap in the wagon like they could in a stroller (they won't tolerate strollers). And then, of course, I'll only do it with one at a time.
