Sonogram results!

We had our 18-week sonogram today and everything looks great. The baby is healthy and growing well, and our due date remains Oct. 8. Nicole and Michael were there and their first question to the sonographer was "is it a boy or a girl?" She tried to take a peek but the baby wasn't being cooperative! So she went about her business taking all of the necessary measurements and showing us all of the various organs, etc. It was great to see the baby's face and moving all around. The kids persisted with "is it a boy or a girl?" and "are you almost done?" God bless this woman for being so patient! So after she ran down her checklist of what needed to be checked, she went back to trying catch a glimpse of the anatomy that we were all so curious about. She froze a picture on the screen and pointed out a little appendage to me. Dumb me asked "Is that what I think it is?" When she said yes I asked her if she was sure that's what it was, and NOT the umbilical cord. I explained to her that a certain someone would certainly have a heart attack if he was told we were having a boy and subsequently gave birth to a girl. She (again very patiently) showed me that the umbilical cord was clearly a very separate entity from our little appendage in question. Nicole was visibly irked that she was not getting her little sister! Michael said "Really? My very own baby brudder?" It was so precious! And of course daddy is thrilled! So much for "mother's instinct" because I would have bet money that we were having a girl!
