The Birthday Jitters

Tomorrow is the big day!
What day is that you ask? Well it's Sione and Liliana's first birthday party. Don't get confused they aren't babies! They are turning six and seven.
But for the last six years we have always had birthdays at church or just family dinner.
Ya see my husband is Tongan, and his church is: "Siasi O' Tonga Tau'a'taina" (which translates to "The Free Church Of Tonga") when you have a birthday at his church(for our family anyway) it's basically just a big feast. We have to prepare all the food and serve it up, a hymn is sung, then a special prayer is said for the birthday child and everyone eats and goes on like it's a normal day.
So that has been our big celebration.
We have had small "parties" where our kids got to have a nice bbq on the actual day of their birthday or special dinner made and presents were given at that time (from immediate family members i.e.:mom, dad, grandpa, grandma, bro.& sis.).

So with all that said I am totally pumped and freaked out all at the same time about tomorrow. I feel like it's the first day of school, I don't know if I should be scared or excited. What if the other kids don't like me kinda feeling! (I know it's wierd right?)
It's almost as if I am questioning myself as a mother, not that party planner has to go on my "mother resume" as I like to call it, I have all the other mother qualifications like: I got them into the world, I hug em, I kiss em, I clothe & feed them, get them to school, change diapers tell them I love em... etc.
But i'm wondering how do I measure up in this world of party planning and such. Like, if I don't get it right this time does that mean we won't do it again? Are my children doomed for life to never have another birthday party... okay okay okay time to slow down! Deep breath. Oh how my mind wanders. See I told you pumped and freaked out!
I guess we will have to see how it goes tomorrow!
Don't worry I'll be back around Monday to either option 1:gush of the fun and games or option 2:cry my eyes out about how terribly it went...
let's hope for sanity's sake that it's the first option!
