My sister isn't jealous, she has three kids, two girls and a boy. But she was so sure i was having a girl so I say she is in denial. I will say, her sons ultrasound does look different, it has a triangle at the end where the tip is and you can't really see his. I also know if I had said her sons didn't look like a penis she would've flipped out on me because they wanted a boy since they had 2 girls. We didn't care either way, we were just excited to know and people just had to rain on our parade.
