Baby shower idea.. Guess the baby's birthday! Great way to replace a guest book. We did this with cut out stickers of a pacifier, rattle, and a cupcake. Each person placed the sticker on the date they predicted and signed their name. Cute idea. Mom-to-be loved it. Cute to put in a scrapbook too!
If they are girls! I probably could do the same thing for boys just less pink and girly frills.
