I have nine week old identical twin girls.
Twin A was 7-7 and her name is Alaina. Twin B was 8 lbs and her name is Patience. My husband named Alaina, I named Patience after a childless family friend.
They were monochorionic diamniotic, the most common presentation for identical twins. Curiously, they're what's called "mirror" twins: their difference in size and Alaina's mildly cruddy eye are their only differences. Well, Alaina's called "Squeaky" for a reason and Patience's name seems to be remarkably suitable, but that doesn't help strangers tell them apart.
I had severe edema with the pregnancy (70 lbs worth) and also developed pneumonia afterwards. It bit the big one.
By the way - hello. Dunno where else to introduce me, but I'm Misty, and I have two other daughters and twins as well. Kyrie died of complications from Down's syndrome before her birth, but Adia is cheerfully snapping pencil lead out of the pencil over by the changing table where she thinks I can't see.
