You can play the diaper game you take a diaper and different chocolate candy and you melt it In the diaper and have to guess what the candy is. Another fun one is taking a bottle and a few people fill the bottle with juice (or milk) and see who can finish it first. Another fun one is you take some baby food remove the label and have people taste it and see who can guess it. For prizes you can get little mini hand sanitizers have lots of fun!
at my baby shower they did that toilet paper game to see how many squares of it, it took to rap around me. and we did the clothes pin game you can't say baby the whole time or whoever hears you get your pin most people do the don't cross your legs one but that's even harder lol.
