You should get some dollar store hula bracelets or necklaces and when each person arrives give them one. If you are having a boy on several pieces of paper write down things that have to do with boys, babyies and mommy. (example) write down; boy, baby, bottle, mom, mommy, blue. Stick the papers around the room. If having a girl write down on the pieces of paper, girl mommy, mom, pink, bottle, newborn, diapers, etc. As your guest arrives tell them about the game. As the day or night goes on your guest will have to pay close attention to what they say and what others say. If you are caught saying one of the words that are on the papers around the room the person that caught you will take your bracelet. Same as if you catch someone saying those words you take their bracelet. At the end of the baby shower who ever has the most bracelets wins a prize!
