I like the one where you put a stack of diapers at the door where everyone comes in whit some sharpie markers. As everyone walks in they writ a funny saying on the front of the diaper ex... this one's gunna stink! So on and so forth. Good luck! Also pintrest is awesome for shower ideals.
You can do a small plastic baby frozen in ice and have clear cups. Have everyone get one, first to have melted or water broke wins. You can also do the tp measureing. Have everyone guess your circumference by just looking and pull amt of tp they think they need. Google games. There are a ton.
Sorry my phone is acting up and posted way too many times. Ugh. Time for new one. Good luck.
Or guess baby food flavor.....
This isnt a game but we did it at my shower, everyone who comes writes their name and address on an envelope(for the thank you cards) and however many center pieces there are, that many envelopes are picked from the pile and whoever is picked gets a centerpiece. Also everyone who brings a pack if diapers is entered into a drawing for a dooerprize... good luck hun, have fun!
