Compile a list of twenty questions about the mommy-to-be. Then ask the Mommy to leave the room for ten minutes and asks the guest questions to see who knows her the best. The guest with the most correct answers wins.
Here is a sample of questions:
What names does she have picked out for the baby?
Does she hope for a boy or girl?
What are the color of her names?
What are the colors she's chosen for the nursery?
What is she wearing today?
What is her favorite children's character (Pooh, Barney, etc.)
Has she had any crazy food cravings?
