*chuckle* I always loved Hudson Hawk.
Pink says it better than I can, so I'm going to snitch her email she sent to friends and family, with a smidge of editing:
We had a sonogram that led to a significant and exciting discovery: the twins are monochorionic! This is a fancy word that means one placenta. The placenta is the part where the two separate umbilical cords attach to the uterus. Having one placenta means two things: 1) there is a risk of a condition called twin-to-twin transfusion syndrome (TTTS) for which I will be monitored by ultrasound every two weeks from June through the end of July; and 2) our twins are identical! Fraternal twins always have two separate placentas, but identical twins can either have two or share one, depending on how many days into the pregnancy they separated. Our twins have one placenta and two amniotic sacs, so they “twinned” between 4 and 8 days after conception.
Twinners. :) So, I either get to do double duty potty training when the time comes...or pay for two weddings. :) Bah, piece of cake!
So, here they are, one snuggled up on the left who was all relaxed (I'm pretty sure she's taking after her mother there), and the one on the right is the top of his head. What you don't see is that he was moving around like crazy tapping on Mom, so he takes after his Dad.
Won't know gender for a while yet...which is why I like to writing confusing paragraphs. :P
