All right, all right. I'll share my secret with you. BUT, it only works if you already have a child. If this is your first baby, I'm sorry, but I can't help you. I have yet to figure out how to determine the sex of the first baby. But, if this is your second, third, fourth, or even fourteenth child, I'll bet I can predict what you're having.
If this is your second child, look at the back of the neck of your first born. Does the hairline across the back of the neck go straight across, or come to a point? If the hairline goes straight across, your baby will be the same gender that your first born is. So, if your first born is a boy, you'll be having another boy. If the hairline goes to a point, your baby will be the opposite gender of what your firstborn is. So, if your first born is a boy, you'll be having a girl!
