Want to know the sex?
I keep telling her that I'm going to find out, and I'll keep it a secret if she wants me to.
A friend of mine says that it is important to know ahead of time because, "what if you're disappointed if the doctor says what you weren't expecting?" You don't want to feel disappointment at your child's birth.
What did they do back in the day when you couldn't tell what it would be? Either way dad's around the world smoked a cigar and said, "yep, I knew it all along."
