Dodo diaper game- you get slightly melted chocolate & rub it in a NB diaper & your guest try to guess what kind of chocolate candy it is :) Also you can google baby shower games. Have fun
We did a 'guess how big mama's belly is' game. I walked around to each table and the guests cut a plastic ribbon (or you can use toilet paper rolls) to how big they THOUGHT I was, then I made everyone come up to me to actually measure. It was nice because it got people laughing and up and out of their seats.
