Party Party Party!!

Alright ladies, you might as well start calling me the questionista, I have two more topics to discuss.

Earlier today my sister called and asked me to help her plan my nieces birthday party because she's not good at planning. My niece will be turning 11. It didn't take long for me to remember that my niece had mentioned a rodeo party. I looked up some stuff and decided we would have the back yard set up like a rodeo with picnic tables and then a place to dance. We would have the guests wear rodeo attire. We will decorate cowgirl hats, play limbo, play dance freeze, twister, stomp the balloon, etc. So I was trying to decide on what foods to cook and what kind of cake to do..any suggestions? And any other tips on games, party favors, decorations, etc?

Next,

My bestie called me to discuss her sons birthday party. He will be turning three. She wants me to help pick out a theme and help her bake the cake and get ready for the party. So ladies, what does a three year old like or what is a cute theme for a three year old? He doesn't watch tv that much, so he isn't a fan of diego or any cartoons. So what does that leave? The only thing I know that he does like is cars and dinosaurs. I need help! Any help is greatly appreciated!

After all of this I am thinking I should change my major to party planning!! I have always wanted to be a caterer and a wedding planne, but around here I wouldn't do good in that line of work, or I may be wrong because we don't have any of those around here :)
