Boy or Girl

My ultrasound is on Friday morning, and I can't wait to find out if this baby is going to be the first Tustison girl (of the grandchildren, not to slight Samantha's double X status) or yet another boy to add to the rising crop of grandsons. I'm curious who is leaning which way. Aiden says he really wants a girl, but last night he told me he thinks it might be a boy. What do you think?
