We threw a party to announce (and find out ourselves) the gender of our first baby.  (A boy!)  At our 20 week ultrasound, we had the ultrasound tech write on a piece of paper if it was a boy or girl and put it in a sealed envelope with the gender revealing ultrasound pictures.  I quickly took the envelope to a close friend to look inside and order a cake with pink or blue filling.  I’ve heard rumors of people taking the envelope to the bakery without someone looking and the bakery made the wrong colored cake or they lost the envelope, so I had a friend look at it to make sure it was correct.  At the party, I had a betting pool where people could bet $ on the date/time/weight of the baby when he is born.  There was an opportunity for people to vote on the sex and then I drew a name out of the correct boy/girl jar and they won a prize.  I had a couple baby pictures of me and my husband up, my pregnancy journal, and old wives tales on what the gender may be, available for people to read for fun.
