I just went and somehow deleted the really long post I'd written with clever links to relevant pages on some of the prescription brands sites - so here goes again, most probably in a more brief format.
You can get sample boxes from Juvela and Glutafin - these are the relevant pages and then you can look around the rest of the site to find the lists of prescription allowances by age, product lists etc.

Juvela
Also take a look at what's available in the supermarket as there are some great products available which are supermarket own brand and not expensive compared to regular products. Doves flour and pasta are excellent and I wouldn't bother with those on prescription to be honest. You can also get great crackers from Trufree and a couple of other brands whose names I can't remember from the supermarket.
Think about what you use regularly for the family and what you can substitute:-
-Sanchi or Clearspring Tamari sauce instead of Soy Sauce which contains wheat (noone will notice the difference)
- Quinoa instead of couscous (although when I tried to give this to my non coeliac 2 year old DD she spat it straight out - slightly different texture). You can also try buckwheat.
- Remember rice is ok and rice noodles are great with Chinese food instead of egg noodles
- Corn tacos/tortillas instead of wheat tortillas (I am having a bit of a Mexican fest at the moment as there are so many wonderful things you can do)
- French mustard and not English mustard which contains wheat
-Make gluten free pancakes (crepe style not American) which can be filled and baked in a sauce similar to a canneloni dish (I do this to make a gluten free canneloni verdi style meal).
-Use gluten free breadcrumbs or coarse polenta or ground almonds to make chicken or fish fingers.
Take a look at Planet Organic and Goodness Direct - you can order things like cereal if breakfast time is tricky and also most other gluten free products if your local supermarkets aren't well stocked.
Just remember, most of all, it's all trial and error - sometimes it will seem hard, sometimes your daughter won't like stuff you buy or make but over time, you'll get there. I was diagnosed nearly 6 years ago and at first it seemed like the end of the world, but now it's a way of life. As an adult, it was much easier to switch, I went through the whole kitchen and pretty much binned all of the gluten and started my new life.
As I mentioned in my last post, I have a stash of baking recipes I can pass on if you'd like, but also, if you want some help with meal planning, I can give you some ideas as we have a mostly gluten free house so my kids only eat regular bread, pasta, biscuits and crackers. Maybe the best way to start is to write a food diary/think backwards of all the food your DD had over the past week before diagnosis and how you could adapt these meals to be gluten free.
Oh, and most Organix snacks, except for the oat bars and the biscuits are gluten free!
