We played "who knows mommy best" you list features such as nose,eye color, temper and have people guess if you want them to have daddy or mommys feature. We also did "daddy knows best" make a list of questions such as "biggest food craving" and ask him. Then at the shower have people guess his answer. Also made little diapers one was "dirty" we just colored yellow in it and whoever got that pin at the end of the shower was the winner.
I played a game at my friends baby shower where they melted 4 different kinds of chocolates(reeces,tootsie rolls, hersheys, and the crisp one) and they passed them around and had guest smell, look, and if they wanted to taste lol it was fun...weird but funny... and the guest had to guess like specific if possible
