Baby shower idea: Guess the baby's birthday! Great way to replace a guest book. You could use stickers of a pacifier and/or a rattle. Each person placed the sticker on the date they predicted and signed their name. Perfect to put in a scrapbook, too!
Diaper Raffle for Baby Shower. Ask guests to bring diapers to the shower for a raffle. Give all the diapers to the new mom and a prize (gift card) or main prize to the raffle winner. Great and easy game for a Baby Shower.
