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!
Measure Mom’s Belly - I think a quick & easy way to do this game is to measure moms belly before the shower & have guests guess how many inches is the belly. The person closes to the right answer wins! No hassle with the string!
