I know of a family, same thing, told on each and every scan it was a boy, and out popped their gorgeous little girl and into a blue bedroom with tonka trucks

I was convinced I was having a boy, nothing concrete, just a "feeling". When we were told she was a girl, I just about fell off the bed. Second scan, I made the sonographer confirm it and she said if it was a boy, he'd need some serious surgery! I don't think I was entirely convinced until she was born.
