Open house baby shower ideas

Kristin
I am throwing myself an open house baby shower and inviting a random amount of friends. I plan on scheduling it from 12-7 so guests can come and go as they please. I am looking for ideas of what to do. I will have a crockpot of chili and some appetizers. I plan on doing some creative activities instead of games. Nothing stationary as people can come and go. Any ideas???
