'My water broke' game for baby showers - My Water Broke! Get a pack of tiny plastic babies at a craft or party store. Freeze one into an ice cube for each guest. After the guests have arrived they all get a cup with the cube in it to keep an eye on during the party. The first person whose ice has melted so that her baby floats freely in the glass shouts "My water broke!" and wins
Dirty Diaper Game - Doorprize (each guest receives one and writes their name on their selected diaper. At the end of the shower the dirty diapers receive prizes.) Easy to make - blue for boy or pink for girl.
