Cecilia at 4 months.
Mary Claire at 5 months.
I'm definitely seeing more differences as Mary Claire gets older - not quite Cecilia's clone, but the face shape and build (and lack of hair) are definitely identical!
Now we just need to put Elizabeth in that dress and do a 3-way comparison!
Seriously, people get so confused when they see us with both babies, because they're never dressed alike and look TOTALLY different. And they finally get it when we tell them they're twins, but it usually takes them a while to figure it out.
I think twins are pretty uncommon in Catholic circles because Catholic women are generally not going to be using fertility treatments that produce twins, and twins are a lot more likely to be conceived when women have just gone off hormonal birth control, so that's another strike against Catholics in the twin game. Statistically, I guess you must see fewer Catholic twins (and we only really see other people at church...)! We certainly never see any, although I know there are some in the blogging world :)
