I like the fairy godmother theme. Here's a link to a website for baby showers, etc. :

It was very helpful when I was planning baby showers as well as my friends bridal showers. They have a vast array of games, etc.
Most of the games are already formatted, all you have to do is print them out. You can vary some of the games to better suit you.
