One of the best ways to get your child excited about their birthday party, as if they need help, is to let them pick out a theme. It seems that most people pick a character or movie for the theme but there are lots of other ideas to choose from. I was going to give you a few examples of great themes, but I found this website that is just chuck full of theme ideas.

Each theme has many examples of ideas to incorporate the theme. Of course, my favorite is the magic theme. But I might be biased. Remember, you can incorporate great entertainment into any theme. Balloon twisting and face painting can be customized for any theme and a magic show fits real nice with lots of the theme suggestions. Have fun planning you party!
