Georgina versus Miriam

I was going through some old photos, looking for ones to print, when I came across some pictures of Georgina that looked just like some I had taken of Miriam last week. Looking at the dates I realised Georgina and Miriam are the exact same age in the photos so they make for a pretty cool comparison.
Can you tell them apart? I'm not going to tell you who's who.

Pretty neat huh?
