Baby shower games...

Amy • I'm 28 and married. Trying to conceive for 8 years and have PCOS. My baby girl is due December 18th!
I know I've seen this post a dozen times, but now its time to start planning my baby shower. We figure it will be like 3 hours, what are some fun games to keep people entertained? We haven't decided on a name yet, so I want to dona name suggestion jar. And I know we are going to do guess the day the baby will be born... But I'm drawing a blank on others. Also, what are some good party favors?
