Re: Silly question...
The 3 lines is what have always been pointed out to us to show it's a girl (with DD1, they showed us the 3 lines, and she came out a girl... this time they showed us the 3 lines too). I would be curious is anyone was ever shown the 3 lines, told it was "a girl," and then ended up having a boy. I assume if the 3 lines are obvious, then it's a girl for sure... but then, I'm not sure how people are told wrong sometimes!
