Mommy Tummy Measure

Using just a few rolls of toilet paper, or ribbon if you prefer, have each guest that arrives take the number of squares off the toilet roll, or cut out the length of ribbon, which they believe is how big mommy’s tummy is at that time. Once everyone has done it, call the mommy-to-be and everyone gets a chance to measure his or her guesses. Whoever is the closest to the right size of mom’s belly wins the game.
