My family came into town and we did a lot of walking and sight seeing. My back was hurting and my husband will let me put my arms around his neck and dangle while he applies pressure on my back. It's very helpful. As we were doing this, a man came up and said "is there two?" My husband was a little taken aback and said "excuse me?" The man asked if we were having twins and we both said yes, quite surprised since I'm only 23 weeks and don't look too enormous yet. "Yeah I can tell, my grandma taught me how to. I can tell that the babies are stacked on top here and here."  He motioned on his own belly exactly the way my twins are laying. My husband was still shocked and said "Are you a wizard ?!" LOL!!!
