Which is Which? Can You Guess?

OK, can you figure out which is which? I thought every time one of my kids was born, "wow, this one looks a lot different!" Then I look at the pics of the other kids when they were newborns and I realize that we turn out little clones...at least at the beginning, then they get their own features. Check it out. There are two of each of them. I put the answers at the bottom, no peeking!
