We're going to find out soon! We just sent off a couple little vials of their saliva for a DNA test. They had their own placentas and sacks which makes it less likely they're identical, but it's still possible and, as you can see from these photos I collected from their short three lives, they often LOOK identical. As I posted on Facebook, you are welcome to offer a guess. As soon as we get the results I'll post again!
