I was going through some of my old pictures on facebook and saw these of Marshall when he was Miller's age:
First of all, oh man I forgot how adorable Marshall was! Secondly, I think they look a little similar right?
Marshall is on the left, Miller on the right.
I need to look through the pictures on my old hard drive and find ones where they are posed the same way, but this one was close. They definitely aren't twins, but they are similar!
