My daughters birthday is soon any ideas for her party?

At four years old I'd still just let the kids rung around playing together. But, you can get a pinata, they make ones with strings to pull instead of having to hit it with a bat. Pin the tail on the donkey is fun for kids. You can take a look at party store websites to see what kind of games they have that may match your party's theme, or you can do a Google search for kid's party games.
