planning the party of the year!

Before I changed my career to full time mommy, I was an event planner. I love planning parties and organizing details. The funny thing is, now I am beginning to plan my kid's 1st birthday and I'm at a loss!! I have no idea what I'm doing and feel completely lost in this venture. Mostly, I think because I want it to be perfect. Not really for her, this party is for me right? We all know it's true. As I am in the process of brainstorming, I just really don't know what to do or what to expect.

Please help out a retired event planner with the most important party of the year! What should I plan for? Some things I should make sure I do and don't do? Good sites to get inspiration? Give me your best planning tips!!

Thanks, you guys rule.
