Compare and Contrast

A few of you have asked if I've compared first photos of the girls. Around here #1 and #2 claim #4 and #5 are twins. Now I'm taking a real look for the first time. Pictures 1 and 2 are truely first photos (as you can see, Anna took more of a beating than Kate did - thank you, Kate). Pictures 3 and 4 are both from their first days at home. From what I can tell, aside from the lack of white hair, Anna is her big sister's twin. You be the judge...
