Number three is a boy.
Looks like Berlin will be the only sister in the house. We had the ultrasound done this morning and discovered (quite clearly) that our third and final installment into the family is, indeed, a boy. Jamison went with us to the ultrasound. He was confused because he thought the baby was going to come out. He didn't seem to see what all the excitement was about. But when we told him that he was going to be a big brother to a little brother, a huge grin crossed his face. He'll be happy to not be the littlest in the house anymore.
