I'm new to Celiac and need help

Hi - My 7 year old granddaughter was recently diagnosed with Celiac 
Disease.  She was diagnosed with Type 1 Diabetes in March.  It is 
difficult for her to be on a gluten free diet since she is a picky eater 
and only wants to eat pizza, mac & cheese, etc.  Can you give me help 
with meal planning?  I am reading many cookbooks including Bette 
Hagman's books, Carol Fenster's books among others.  Her Aunt and I have 
been buying gluten free flours and putting together flour blends to bake 
goodies for her.  Her Mother has been overwhelmed with these diagnoses 
and because of work hours does not have the time to do much meal 
planning.  They live in Oregon, we are in Maryland and I plan to fly out 
to help them. Thanks for any help you can give to me.    Rusty in MD
