It's a girl!
I was so happy to hear those words. When my daughter was born, the nurse was taking all of her vitals, and she said, "Congratulations, Dad, you have a baby girl!" She then took my little girl's foot and covered it in ink to take a footprint. That footprint was then mashed on the back of my hand, and the nurse said, "Get used to it, Dad, this isn't the last time she's going to walk on you."
