Do you see the resemblance?

When my mom saw the pictures of Aaron on facebook, she thought that I had reposted old pictures of Matt when he was a new born. They do look quite alike. I went through some old pictures of Matt and my goodness, Matt and Aaron could be twins! :) Which one is which??

The first one is Matthew shortly after he was born. The second one is Aaron. Don't they look a lot alike?? I love it! :)
