Guess the Gender...

The girls at work are having so much fun guessing the gender of the baby, they even put up two little jars in the break room, one with a blue rattle and another with a pink one.  They are having people guess which sex we are having by writing their names on a little piece of paper and putting it in the jar of their choice. 

I hear there is a fun prize for the winning "gender team"! 
Who will win?  Find out tomorrow?
