Give me some ideas for my son's birthday party.

There are several ways to plan a fun and engaging birthday party for your son.  To get started, it would be helpful to consider your son's interests.  From there, you can set that thing of interest as a theme and plan your party around it.  For example, let's say your son loves the car.  In that scenario, you could decorate the event space with car-related stuff and perhaps even order a cake shaped like a car!
