Most moderators do not bite and if something is in the wrong place then they magically move it to the right spot. I never seen it done but seen on the boards a note saying something was moved.
First of all you need to work on your child's needs. There are many threads on specific illnesses as well as special needs. FAQs should find you something to help make her trip more enjoyable. Among the things you may want to look at is diet, needs shade, tires easy, her medical needs, special feeding.
Next is the Wish Trip Organization. There is a wonderful place for Make a Wish kids in the WDW area and you can read up on what goes on there. They can help you know what you might get on the trip and what cannot be done.
This board and the transportation areas can help you with getting to and from WDW. Like what to do on the plane, how to get a kid through TSA without them freaking out (scary even for me, lol), what you can take on the plane like syringes and food, and transportation to and from the airport.
Various boards can help you with ideas like decorating a kid's wheelchair, fun kid things to do, best spots to watch a parade, discounts, and ride closures. For a kid you can do a scrap book for example or a photo book. Matching family t-shirts is another idea.
Just take a deep breath and break down the trip into bite size bits like where to eat, what to see, special needs, and the transportation. If you get overwhelmed then make an itinarary and a folder for notes to keep in one place in the house so you can double check things. I have on my computer notes for my last trip to San Antonio and lists of bookmarks and notes for my trip to new Hampshire. On the computer you can set a bookmark like "Wish Trip" then put subfolders like the transportation, resort, make a wish, things to do. For my trip i have hotels, things to see, transportation, convention, EATING, and other stuff as labels for my subfolders.
Breath in, breath out.
