If someone's expecting a baby and you want to throw a baby shower for her, here are some games you can play during the party:
1. Guess mom's tummy size: We passed around a ball of yarn and each person would cut off the length of yarn that they thought would fit around the mom's belly. The person who was the closest got a prize.
2. Guess the baby food flavor: We had a bunch of baby food jars that we tore the labels off of so none of the guests knew what flavor it was. Each person tasted them and whoever got the most right won something.
3. Guess the due-date: Pretty self-explanatory although this would only work if your guests didn't already know the due-date.
For party favors, if you have a bit of money to spend or if you're only throwing a small party, you could go to a party supply store and get mini-bottles and fill them up w/ jelly-beans. If you're lucky you might be able to find mini-bottles (or something similar like mini-baby booties) at a dollar store. That would certainly cut down on cost!
