Twins?

It has been pointed out to me that Penelope looked just like Flynn when he was a baby. I didn`t think so at first... aside from the black hair. I mean, I can see they're siblings but Penelope's eyes, nose and mouth are very different. Flynn had the biggest mouth I've ever seen on a baby and Penelope's mouth is so tiny. But then we took some pictures for our baby announcement cards, and for one of the shots, we had Penelope pose the same way as Flynn when we took his pictures. And wouldn't you know it? They look pretty much alike after all!
